A Momentum Space Approach to Improve , Hartree-Fock Results Based on the LCAO-GTF Approximationh have inherent deficiencies. A preliminary study toward a systematic use of the iteration-variation method expressed in momentum space to improve molecular properties calculated at the Hartree-Fock level by standard quantum chemistry methods is presented. The results obtained for the hydrogen atom,

Møller Plesset Calculations with Explicitly Correlated Wave Functionspendent pair correlation functions, which takes care of the correlation cusp. The calculated second-order pair energies are accurate to within a few millihartree in comparison with the estimated exact values. In particular, second-order energies of 425.1, 819.0, 360.3 and 265.9 mE. have been obtaine

Basic Mathematical Properties of Electronic Wave Functions in Momentum Spacehe Schrödinger equation in momentum space is discussed and singular points for the amplitudes are located. An exact local potential is described and the associated amplitude is examined. Other examples illustrating the importance of complex function theory in momentum space are described.
