Recent Developments in Noncovalent Interaction Methods

The development of noncovalent interaction methods has been a long journey since the first use 40 years ago. Enormous efforts have been made, starting from a simple semiempirical approach to a complex wavefunction approach. In this review, we will first discuss a classification of molecular forces, followed by the recent method development of noncovalent interactions. Mainly, we will focus on dispersion-corrected methods in density functional theory, semiempirical molecular orbital, and wavefunction-based approaches.
