The effects of molecular angular momentum (spin polarization) on the bulk viscosity and relaxation time in a multicomponent gas mixture are considered. Formal theoretical results are obtained, using the Wang Chang-Uhlenbeck approach to the kinetic theory of gases with internal states. The results are given in terms of integrals over the weighted quantum mechanical degeneracy averaged cross section.
