Abstract
Time-dependent coupled Hartree–Fock frequency-dependent polarizabilities have been corrected for true correlation effects by means of many-body perturbation theory. Polarizabilities have been computed for the monomers He, Ne, H2, and N2 through second order in the correlation potential. With these polarizabilities as input the van der Waals coefficients of all possible dimers have been obtained by the use of the Casimir–Polder relation.Keywords
