Abstract
Classical expressions for the generalized or kinetic theory cross sections for gases of diatomic molecules derived earlier are specialized to describe atom–diatomic molecules collisions and developed further. Numerical results based on parameters intended to describe Ar–N2 collisions are then presented and the resulting generalized cross sections are compared with those derived from experimental studies of the Senftleben–Beenakker effect on the viscosity of mixtures of argon and nitrogen. The results indicate that the experimental values may be reproduced using reasonable values of the anisotropy parameters.
