Abstract

Low temperature, phaseโ€equilibria data for binary systems containing hydrogen, helium, and neon were used to develop a correlation relating deviations from the geometric mean combining rule for the characteristic energy parameter to the ionization potentials of the component species. With the exception of oxygen systems, this relatively simple relationship correctly predicts published deviations, determined by different methods, for a number of systems within expected uncertainties. It is shown that consideration of attractive forces only, as done by Hudson and McCoubrey, is inadequate for such predictions.

The addition of a solid to a mixture of small molecules introduces variations on the average translational mobility of these latter, proportional to the affinity of a given moiety for the less-mobile phase. This effect is at the basis of chromatographic separation, but can be used to simplify the NM

Working on a mesoscopic scale, a new cubic expression for the effective permittivity of mixtures as a function of the mean permittivity fluctuation is established. Using previous methods for calculating this mean value, the effective permitivity of a mixture can thereby be written as a function of t
