✦ Synopsis

A new version of a formerly proposed integral equation is presented. This new equation is valid, as is the previous one, for linear molecules interacting via a Kihara potential. It is used to obtain the average surface-surface correlation function of CO*.

The differences in calculated thermodynamic properties as compared with the former version are not great except for the virial pressure. The range of thermodynamic states for which the calculated equation of state gives good agreement with experiment extends into a region where most perturbation theories and integral equations yield poor results.
