Quantum chemistry is a part of theoretical chemistry and physical chemistry concerned with the application of quantum physics to chemical problems: type and strength of chemical bonds, compound formation of atoms and molecules, conjugation, resonance, hybridization, aromaticity, the description of the electronic structure of atoms and molecules and the effects on their reactivity etc.
Quantum mechanical studies on atoms are regarded as the boundary line between chemistry and physics and are not necessarily assigned to quantum chemistry.
The basis for most quantum chemical methods is the Schrödinger equation. However, since this can only be solved for very simple systems even within the Born-Oppenheimer approximation, further approximations must be introduced.
Main tools of quantum chemical considerations are mathematical models that approximate methods, density functional theory and mainly computational chemistry.
