The Calculation of Atomic and Molecular Electron Binding Energies,lso recognized early [2] that ground state Hartree-Fock . orbital energies (according to Koopmans’ theorem) can with some success be used as measures of valence electron binding energies, while core ionization energies are rather poorly represented in this manner.

This term is here taken in a general sense to encompass a set of two-time Green’s functions, such as used by Yngve ?hrn and the present author in our textbook [1], There will not be time to present the arguments leading to the appearance of the polarization propagator as the natural quantity fo

The theory behind this approach is very straightforward but in applying it to practical problems of chemical interest certain computational problems arise, particularly if it is desired to extend the calculations to the limit of a full CI in a large AO basis.
