Abstract
The general interrelation of the theoretical first approximations to viscosity, self‐diffusion, and thermal diffusion previously derived is modified to conform with a simpler and more accurate approximation for the thermal diffusion ratio due to Kihara. The accuracy and limitations of this interrelation are discussed, with particular regard to the effect of considering higher approximations to the transport properties. With the recently published results for the modified Buckingham potential as a guide, the relation is further simplified, leading in particular to an approximate relation between viscosity and thermal diffusion which is shown to be in good agreement with the experimental data for argon.Keywords
