Overview

Quantum chemistry, also known as molecular quantum mechanics, is a branch of Physical Chemistry that applies Quantum Mechanics to chemical systems. This field focuses on the quantum-mechanical calculation of electronic contributions to physical and chemical properties of Molecules, Materials, and solutions at the atomic level. Quantum chemistry is concerned with the computation of quantum effects on Molecular Dynamics and Chemical Kinetics. The calculations involved in quantum chemistry include systematically applied approximations intended to make calculations computationally feasible while still capturing as much information about important contributions to the computed Wave Functions as well as to observable properties such as Structures, Spectra, and Thermodynamic Properties.
