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.
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.
A general discussion of the Gruneisen parameter is Riven and the use to which it may be put in developing a theory of molecular crystals. Calculsiions are made to effect a comparison between theory and experiment for the lattice Raman bands of crystalline nitrogen (o-form) and their variation with p
