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, H/sub 2/, and N/sub 2/ 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.
