Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular orbitals, orbital interactions, and molecule activation.
In theoretical chemistry, chemists, physicists, and mathematicians develop algorithms and computer programs to predict atomic and molecular properties and reaction paths for chemical reactions. Computational chemists, in contrast, may simply apply existing computer programs and methodologies to specific chemical questions.
Molecular modelling encompasses all methods, theoretical and computational, used to model or mimic the behaviour of molecules. [1] The methods are used in the fields of computational chemistry, drug design, computational biology and materials science to study molecular systems ranging from small chemical systems to large biological molecules and material assemblies.
Computational and Theoretical Chemistry is a peer-reviewed scientific journal published by Elsevier. It was established in 1985 as Journal of Molecular Structure: THEOCHEM, a spin-off of the Journal of Molecular Structure. It obtained its current name in 2011 and covers molecular structure in theoretical chemistry.
Kenichi Fukui (1918–1998), Japanese theoretical chemist, 1981 Nobel Prize in Chemistry winner for theories of chemical reactivity Richard A. Friesner (1952–), developer of Jaguar Laura Gagliardi (1968–), known for her work on the development of electronic structure methods and their use for understanding complex chemical systems
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 ...

Molecular descriptors play a fundamental role in chemistry, pharmaceutical sciences, environmental protection policy, and health researches, as well as in quality control, being the way molecules, thought of as real bodies, are transformed into numbers, allowing some mathematical treatment of the chemical information contained in the molecule.
