Direct Determination of the Intermolecular Potential of Kr-N2, Xe-N2 and He-SF6 form the Extended Principle of Corresponding States

Abstract

A more direct semi-empirical inversion has been developed that
obtains a non-parametric potential from experimental data The
method is iterative and coverage rapidly once a good choice has
been made for the initial starting potential. To be specific. the aim
of an inverse method is to obtain the potential by considering the
experimental data as a functional, instead of fitting the data to a
constrained potential for having a few parameters. The interaction
potentials are estimated for the Kr—N₂,  Xe—N₂ and He—SF₆ and
comparisons of the potentials with the earlier values were made.
The resulting potentials were used to predict the diffusion coefficient
for Kr—Ne.
