t. e. Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria . Physical chemistry, in contrast to chemical ...
The relationship between chemistry and physics is a topic of debate in the philosophy of science. The issue is a complicated one, since both physics and chemistry are divided into multiple subfields, each with their own goals. A major theme is whether, and in what sense, chemistry can be said to "reduce" to physics. [ 1][ 2]
Chemical physics is a branch of physics that studies chemical processes from a physical point of view. It focuses on understanding the physical properties and behavior of chemical systems, using principles from both physics and chemistry. This field investigates physicochemical phenomena using techniques from atomic and molecular physics and ...
chemical physics, the science of physical relations in chemistry. computational physics, the application of computers and numerical methods to physical systems. econophysics, dealing with physical processes and their relations in the science of economy. environmental physics, the branch of physics concerned with the measurement and analysis of ...
Molecular physics is the study of the physical properties of molecules and molecular dynamics. The field overlaps significantly with physical chemistry, chemical physics, and quantum chemistry. It is often considered as a sub-field of atomic, molecular, and optical physics. Research groups studying molecular physics are typically designated as ...
However, the term "physical" creates an unintended, somewhat arbitrary distinction, since many branches of physical science also study biological phenomena (organic chemistry, for example). The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
Molecular physics, while closely related to atomic physics, also overlaps greatly with theoretical chemistry, physical chemistry and chemical physics. [4] Both subfields are primarily concerned with electronic structure and the dynamical processes by which these arrangements change. Generally this work involves using quantum mechanics.
Physical organic chemistry is the study of the relationship between structure and reactivity of organic molecules.More specifically, physical organic chemistry applies the experimental tools of physical chemistry to the study of the structure of organic molecules and provides a theoretical framework that interprets how structure influences both mechanisms and rates of organic reactions.
