Concept Info

NAME

Physical chemistry

DESCRIPTION

Physical chemistry is one of the traditional sub-disciplines of chemistry and is concerned with the application of the concepts and theories of physics to the analysis of the chemical properties and reactive behaviour of matter. While also at the interface between physics and chemistry, it is distinct from chemical physics.

Biophysical chemistry is also used to describe techniques suited to understanding the physical properties of biological molecules at a chemical level, including nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography.

95 skos:definition Electron transfer is a process by which an electron moves from one atom or molecule to another. It is a key concept in redox chemistry – the chemistry of reactions where one reaction partner loses electrons (oxidation) while the other gains electrons (reduction).

102 skos:broader sg:ontologies/subjects/physical-chemistry
103 skos:definition Energy transfer is the process by which energy is relocated from one system to another, for example, through the transfer of heat, work or mass transfer. In chemistry, the affect of atomic or molecular composition on energy transfer is studied, examples of which include energy transfer through molecular collisions or through fluorescence resonance energy transfer.

111 skos:definition Excited states are those quantum states of an atom or a molecule with more energy than the ground state. The understanding of excited states and their relaxation to lower energy states plays an important role in spectroscopy and also lies at the heart of photochemistry.

119 skos:definition Reaction kinetics and dynamics refers to the study of why, how and how fast chemical processes take place. Chemists seek to understand the details of change at the molecular and quantum level and how such reactivity can be affected, pushing the boundaries of technology and theory to do so.
