WebPost–Hartree–Fock. In computational chemistry, post–Hartree–Fock [1] [2] ( post-HF) methods are the set of methods developed to improve on the Hartree–Fock (HF), or self-consistent field (SCF) method. They add electron correlation which is a more accurate way of including the repulsions between electrons than in the Hartree–Fock ...
