A revised analysis of the effect of long-range nonspherical terms in the
intermolecular potential on the second virial coefficient is presented with a
preferred Hartree-Fock-Dispersion functional (HFD-C) spherical core treatment
of the integrations for small intermolecular distances. A set of modified numerical
tables for the accurate calculation of the nonspherical contribution to the
second virial coefficients is presented and a new correlation equation of B~O
for C02, CS2 and C6H6 is reported
