in previous papers, we presented an evaluation of the dispersion energy, using a double perturbation scheme and an "Epstein-Nesbet partition" of the individual molecular harn~ton~n~ The purpose of the present work is to check whether such dispersion energies, added to the SCF supermolecuie energies,
An analysis of regularities m the van der Waals forces has been performed for over fifty systems. Correlauons are found betueen features of the interactIon. namely the well depth and tts IwzatIon, and atomic propertles such as the polartzabihty. These correlanons can be extended to the spherical par
