11^th World Congress on Physical and Theoretical Chemistry March 21-22, 2023 Paris, France

Track 1: General Physical Chemistry

Physical Chemistry is the branch of chemistry dealing with the physical properties of chemical substances. It is one of the traditional sub-disciplines of chemistry and is related with the application of the concepts and theories of physics to the study of the chemical properties and reactive behaviour of matter.

Track 2: Physical Chemistry of Macromolecules

Physical Chemistry of Macromolecules employs the combined principles of physical chemistry to define the behaviour, structure, and intermolecular effects of macromolecules in both solution and bulk states. It emphasizes the statistical measures of structure and weight distribution, and also discusses structural, dynamic, and optical properties of macromolecules in solution.

Track 3: Theoretical Chemistry

Theoretical chemistry is the discipline that uses quantum mechanics, classical mechanics, and statistical mechanics to explain the structures and dynamics of chemical systems and to correlate, understand, and predict their thermodynamic and kinetic properties. Modern theoretical chemistry may be roughly divided into the study of chemical structure and the study of chemical dynamics. The former includes studies of: (a) electronic structure, potential energy surfaces, and force fields; (b) vibrational-rotational motion; and (c) equilibrium properties of condensed-phase systems and macro-molecules. Chemical dynamics includes: (a) bimolecular kinetics and the collision theory of reactions and energy transfer; (b) unimolecular rate theory and metastable states; and (c) condensed-phase and macromolecular aspects of dynamics.

Track 4: Chemical Kinetics

Chemistry, by its very nature, is related with change. Substances with well-defined properties are converted by chemical reactions into other substances with distinct properties. For any chemical reaction, chemists try to find out the practicality of a chemical reaction which can be predicted by thermodynamics, extent to which a reaction will continue can be determined from chemical equilibrium and speed of a reaction i.e. time taken by a reaction to reach equilibrium. Along with viability and extent, it is equally important to know the rate and the factors controlling the rate of a chemical reaction for its thorough understanding. For example, which parameters determine as to how rapidly food gets spoiled? How to design a rapidly setting material for dental filling? Or what controls the rate at which fuel ignites in an auto engine? All these questions can be answered by the branch of chemistry, which deals with the study of reaction rates and their mechanisms, called chemical kinetics.

Track 5: Chemical Physics

Chemical physics is a sub field of chemistry and physics that investigates physicochemical phenomena using techniques from molecular and atomic physics and condensed matter physics; it is the branch of physics that studies chemical processes from the point of perspective of physics. While at the interface of physics and chemistry, chemical physics is distinct from physical chemistry in that it focuses more on the typical elements and theories of physics. Meanwhile, physical chemistry observes the physical nature of chemistry. Nonetheless, the distinction between the two fields is vague, and workers usually practice in both fields during the course of their research.

Track 6: Radiation Chemistry

Radiation chemistry indicates the chemical effects of interactions of ionizing radiation with materials. The term ionizing radiation in a wider perception is also applied to photons or particles having sufficient energy to ionize the molecules of the medium: it involves photons with energies differ from the first ionization energy of the medium (~ 10 eV) up to some million eV (MeV), as well as energetic charged particles, electrons, positrons, accelerated heavy ions, etc. In a narrower perception, only those radiations are considered in radiation chemistry, whose energies are several series of magnitude higher than the energies of the chemical bonds. The result of the energy absorption is breaking or rearrangement of chemical bonds; i.e. decomposition of some of the beginning molecules and formation of new ones. High-energy photons, charged species with adequately high energy and neutrons might be absorbed by the nuclei and cause nuclear reactions.

Track 7: Femtochemistry

Femtochemistry is the field of physical chemistry that studies chemical reactions on extremely short timescales, about 10−15 seconds. The steps in some reactions occur in the femtosecond timescale and sometimes in attosecond timescales, and will few times form intermediate products. These intermediate products cannot always be concluded from observing the starting and end products. Femtochemistry enables exploration of which chemical reactions take place, and investigates why few reactions occur but not others. The resolution in time of the elementary dynamics (femtochemistry) offers an opportunity to observe a molecular system in the continuous process of its evolution from reactants to transition states and then to products. Application of femtochemistry in biological studies has helped to elucidate the conformational dynamics of stem-loop RNA structures.

Track 8: Geochemistry

Geochemistry is the science that utilizes the tools and principles of chemistry to explain the mechanisms behind significant geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System and has made significant contributions to the understanding of a number of procedures including mantle convection, the formation of planets and the origins of granite and basalt.

Geochemists study the composition, structure, procedures, and other physical aspects of the Earth. They examine the distribution of chemical elements in rocks and minerals, as well as the movement of these elements into soil and water systems. There is a plenty of information buried in the liquids, gases, and mineral deposits of rock. The geochemist’s job is to understand this information and make well informed decisions on a range of industrial and scientific research applications. Understanding the chemical constitution of rocks tells oil companies where to drill for oil; enables scientists to put together broad-based hypothesis about the way the Earth is changing; helps environmental management companies decide how to discard of a toxic or hazardous substance; and  steers mining companies toward use of natural resources with a minimum environmental impact.

Track 9: Astrochemistry

Astrochemistry is the study of chemical constituents found in outer space, generally on larger scales than the Solar System, especially in molecular gas clouds, and the study of their formation, interaction and destruction. As such, it represents an overlap of the areas of astronomy and chemistry. On the Solar System scale, the study of chemical elements is usually called cosmochemistry.

Astrochemists conduct experimental and computational laboratory studies (including quantum chemical calculations) to generate data for interpreting astronomical observations, to provide input data for models, and to test theories about the formation and evolution of big and small molecules in various astrophysical environments. They also use Earth-based telescopes, satellites, and space vehicles to collect spectroscopic data. They create and apply mathematical models, theories established on chemical dynamics, kinetics, quantum mechanics, and other physical principles. They use computer visualizations to support them elucidate their observations in terms of known physical and chemical principles and to study the origins of extraterrestrial bodies and the chemical procedures that have shaped their present forms.

Track 10: Photochemistry

The study of chemical reactions, isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is known as Photochemistry. Photochemistry is the underlying mechanism for all of photobiology. When a molecule absorbs a photon of light, its electronic constitution changes, and it reacts differently with other molecules. The energy that is absorbed from light can effect in photochemical changes in the absorbing molecule, or in an adjacent molecule (e.g., photosensitization). The energy can also be set off as heat, or as lower energy light, i.e., fluorescence or phosphorescence, in order to    give back the molecule to its ground state. Each type of molecule has a different preference for which of these different mechanisms it utilizes to get rid of absorbed photon energy, e.g., some prefer fluorescence over chemistry.

The Basic Laws of Photochemistry are,

o    The first law of photochemistry, the Grotthuss-Draper law, states that light must be absorbed by a compound in order for a photochemical reaction to occur.

o    The second law of photochemistry, the Stark-Einstein law, states that for every photon of light absorbed by a chemical system, only one molecule is activated for subsequent reaction. This "photoequivalence law" was derived by Albert Einstein throughout his development of the quantum (photon) theory of light.

Track 11: Quantum Chemistry

Quantum chemistry is a field of chemistry whose primary focus is the application of quantum mechanics in physical models and experiments of chemical systems. It is also known as molecular quantum mechanics. Quantum chemistry is the application of quantum mechanical theories and equations to the study of molecules. In order to understand matter at its most fundamental measure, we must utilize quantum mechanical models and methods. There are two aspects of quantum mechanics that make it differ from previous models of matter. The first is the concept of wave-particle duality; that is, the notion that we want to think of very small objects (such as electrons) as having characteristics of both particles and waves. Second, quantum mechanical models precisely predict that the energy of atoms and molecules is always quantized, meaning that they may have only certain amounts of energy. Quantum chemical theories allow us to elucidate the structure of the periodic table, and quantum chemical calculations allow us to accurately predict the structures of molecules and the spectroscopic behaviour of atoms and molecules.

Track 12: Solid-state Chemistry

Solid-state chemistry, also sometimes mentioned to as materials chemistry, is the study of the synthesis, structure, and properties of solid phase materials, peculiarly, but not necessarily exclusively of, non-molecular solids. Solid-state chemistry continues to play an amplifying role in an astounding array of disciplines. As the discovery of new physical phenomena has often depended on the progression of new materials, the synthesis of new solid-state materials and kinetically solid composites with optimized properties is of central importance. While solid-state materials have historically been developed through high temperature solid-state reactions, generally affording the most thermodynamically stable phases, a variety of techniques have been developed to master the limitations inherent in this traditional approach.

Track 13: Spectroscopy

Spectroscopy is study of the absorption and emission of light and other radiation by matter, as related to the dependence of these procedures on the wavelength of the radiation. More recently, the definition has been expanded to include the study of the relations between particles such as electrons, protons, and ions, as well as their interaction with other particles as a role of their collision energy. Spectroscopic analysis has been crucial in the development of the most fundamental hypothesis in physics, including quantum mechanics, the special and general theories of relativity, and quantum electrodynamics. Spectroscopy, as applied to high-energy collisions, has been a key tool in developing scientific consideration not only of the electromagnetic force but also of the strong and weak nuclear forces.

Track 14: Surface Science

Surface science is the study of physical and chemical phenomenon that occur at the interface of two phases, including solid–liquid interfaces, solid–gas interfaces, solid–vacuum interfaces, and liquid–gas interfaces. It includes the fields of surface chemistry and surface physics. Surface chemistry can be roughly defined as the study of chemical reactions at interfaces. It is closely associated to surface engineering, which aims at modifying the chemical composition of a surface by incorporation of selected elements or functional groups that generate various desired effects or improvements in the properties of the surface or interface.Surface science is of specific importance to the fields of heterogeneous catalysis, electrochemistry, and geochemistry.

Track 15: Physical Organic Chemistry

Physical chemistry is the study of the link between structure and reactivity of organic molecules. a lot of specifically, modern physical chemistry applies the experimental tools of chemistry to the study of the structure of organic molecules and provides a theoretical framework that interprets however structure influences each mechanisms and rates of organic reactions. It will be thought of as a subfield that bridges organic chemistry with physical chemistry. Physical organic chemists use each experimental and theoretical disciplines like spectrum analysis, chemical analysis, natural philosophy, and process chemistry, and scientific theory to check each the rates of organic reactions and also the relative chemical stability of the beginning materials, transition states, and product. Chemists during this field work to know the physical underpinnings of chemistry, and thus physical chemistry applications in specialised areas as well as chemical compound chemistry, supramolecular chemistry, chemical science, and chemical science.

Track 16: Thermochemistry

Thermochemistry is the study of the heat liberated or absorbed as a result of chemical reactions. It is a branch of thermodynamics and is used by a wide range of scientists and engineers. Thermochemistry focuses on these energy changes, particularly on the system's energy exchange with its surroundings. For example, biochemists use thermochemistry to understand bioenergetics, whereas chemical engineers apply thermochemistry to depict manufacturing plants. Chemical reactions involve the conversion of a set of substances inclusively referred to as "reactants" to a set of substances collectively referred to as "products."

Track 17: Biophysical Chemistry

Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems. The most common feature of the research in this subject is to seek explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the supra-molecular structure of these systems. Biophysical chemists employ various techniques used in physical chemistry to probe the structure of biological systems. These techniques include spectroscopic methods such as nuclear magnetic resonance (NMR) and X-ray diffraction.

Importance and scope of Physical Chemistry 

Physical chemistry is the study of how matter comports on a molecular and atomic level and how chemical reactions occur. Physical chemistry blends the principles of physics and chemistry to study the physical characteristics, or properties, of molecules. By understanding these properties, you learn more about the way in which molecules are put together, as well as how the genuine structure of a chemical is impacted by these properties. Within the field of physical chemistry, we can investigate how molecules or atoms coalesce to compose particular molecules. We can additionally learn about the distinct properties of matter, such as why a compound burns or about its ability to convert from a liquid to solid substance. Indubitably, this field is very paramount in the world of science, especially as it paves the way for the revelation of incipient theories.

Based on chemical reaction analyses, physical chemists may develop incipient theories, such as how complex structures are composed. Physical chemists often work proximately with materials scientists to research and develop potential uses for incipient materials. Many people trained as physical chemists ultimately work as analytical chemists, where they work to understand the fundamental procedure involved in analytical techniques, sanctioning them to enhance and expand those techniques.

Physical chemists are fixated on understanding the physical properties of atoms and molecules, the way chemical reactions work, and what these properties disclose. Their work involves analysing materials, developing methods to test and characterize the properties of materials, advancing theories about these properties, and discovering the potential utilization of the materials. Utilizing sophisticated instrumentation and equipment has always been a paramount aspect of physical chemistry. Most physical chemistry labs are plenary of analytical instruments, which can include lasers, mass spectrometers, nuclear magnetic resonance, and electron microscopes.
