Abstract
Perturbation techniques are used to derive an analytical expression for the thermal diffusion coefficient for isotopic, polyatomic gas mixtures. The expansions isolate the contributions to the thermal diffusion coefficient which are subject to isotopic variation and elucidate the effect of external fields on the phenomena.Keywords
