Model Calculations of Transport Coefficients for Diatomic Gases in an External Magnetic Field

Abstract

The geometry of rigid, convex molecular models in collision is discussed. Transport coefficients of diamagnetic, diatomic gases are computed in field-free space and in a static field using these models. The calculated transport coefficients are compared with the approximate analytical results of McCourt and Snider and Levi and McCourt. It is shown that the terms odd in the angular momentum make only a small contribution and are, in fact, zero in the approximation of Levi and McCourt. The viscosity is found to provide a more sensitive test of the models than does the thermal conductivity, and the reasons for this are explored.
