Foil 10 The Hartree-Fock (SCF) Method

From Overview of NPAC Research in Computational Chemistry Visit by CEWES Team -- Mar 25 1997. by David Bernholdt *
Each electron sees average field of other electrons
Iterative procedure to achieve a self-consistent field
Result is the familiar molecular orbital (MO) picture
Core of computation: construction of Fock matrix:
Fmn¬ Dls {2(mn|ls)-(ml|ns)}
(Gaussian) basis functions {cm} used to expand wave function
Integrals (mn|ls) are Coulomb repulsions of electrons in specific basis functions
