Abstract
The second refractive virial coefficient has been computed for Ne, Ar, Kr, Xe, CH4, and SF6 using the best empirical intermolecular potentia ls available and a model for the pair polarizability trace which accou nts for both long-range and short-range effects. The results are compa red with experimental data from the literature. It is found that the o verlap contribution to the pair polarizability trace is significant an d can be reasonable modeled with an exponential term.
