Computational chemistry involves the use of computers to investigate the structure and properties of atoms, molecules, and molecular aggregates. There is great overlap and some confusion between the disciplines commonly called "computational chemistry", "molecular modeling", and "theoretical chemistry". To simplify, all of these are grouped under the computational chemistry ODP category, except for some sites that go to Science / Chemistry / Physical.
