MORSE POTENTIAL FUNCTIONS FOR NONPOLAR GASES,

Abstract

'Most likely' Morse potential functions for Ne, Ar, Kr, Xe, N2, and CH4 are determined from experimental second virial coefficient and viscosity data. By employing variants of the usual statistical fitting procedures, the elucidation of different features of the potentials is emphasized. The 'most likely' potentials give a better description of the experimental second virial coefficient and viscosity and repulsive scattering potentials than do those based largely on crystal properties. The Morse potential is apparently less suitable than the Kihara potential for reproducing the experimental second virial coefficient and viscosity at least for Ar; neither model is able to reproduce both properties within the limits of experimental error. A comparison is made with other selected model potentials. (Author)
