Second virial coefficient and viscosity data were used to evaluate intermolecular potential functions proposed in the literature for SF{sub 6}, UF{sub 6}, and WF{sub 6}. It was found that none of the potentials could predict the properties simultaneously. By suitable adjustment of the repulsive wall, we constructed an inverse power (n{minus}7) potential which correlates second virial coefficient and viscosity data at the same time. The best integer repulsive exponent for SF{sub 6} was found to be n = 40, while that for UF{sub 6} and WF{sub 6} was n = 46. 41 refs., 10 figs., 11 tabs.
