✦ Synopsis

Some of the pathways which connect the macroscopic properties of gaseous systems with the dynamics of binary encounters between their constituent molecules have been traveled frequently in both directions, Even so, there remain unknown stretches along the most familiar trails, and prospective routes for most polyatomic molecular systems have not been traversed in even one direction. Not long ago, Chu, Chappelear, and Kobayashi (1975) analyzed experimental data on diffusivity, viscosity, and second virial coefficients for binary mixtures of hydrogen with methane, ethane, propane, and n-butane. By a fitting procedure they determined best values of the molecular interaction parameters ~/ k and u for specifying both a Lennard-Jones ACKNOWLEDGMENT
