Self-consistent field method Guide, Meaning , Facts, Information and Description
The self-consistent field method is a numerical approximation algorithm for solving the Schrödinger equation for isolated molecules in the ground state. The interaction of a single electron in a many body problem with the remaining electrons is approximated by averaging it to resemble a two body interaction. In this way the total energy of a molecule can be obtained. Correlation energy is ignored in this method. Further developments of SCF are CASSCF and configuration interaction. Calculations of this type are normally performed on supercomputers, to date only powerful enough to predict properties of small molecules. Software packages used include Gaussian, Molcas, NWChem, MOLPRO, and GAMESS. Freely available are MPQC and Psi3.This is an Article on Self-consistent field method.
