β¦ Synopsis
A nex simple function which is capable of representing the intermolecular pair potential energy of tic kert gases is proposed. It is based on the traditional n-6 rcciprocaf power poten..iaI with the modification that n is regarded iis a function of separation rather than as a constant.

An empirical intermolecular potential energy function with two adjustable parameters is proposed for quasi-spherical, non-polar molecules. Calculation of the second virial coefficients of methane, xenon and fluoromethane shows that the model is comparable with three-parameter potential functions.
