Using Ar" -Ar" as calibrating gas, the simultaneous deterrnination of thermal diffusion factorsa-p's at two available experimental temperatures as well as the prediction of pressure dependenceof In q. at an intermediate temperature is possible for some isotopic inert gas mixtures in terms ofcolumn calibration factor F. (CCF) of a given column. The variation of a-7 with T is then usedto estimate the force parameters of the molectrles only to ensure the reliability of the proposedtemperature dependence of a-p. The experimental<a-p's due to Maxwell and Slieker shape factorsare also calculated for comparison with those by the CCF method as well as by theoretical onesbased on elastic collisions among the molecules, It seerns that cv7's by CCF method play animportant role in determining the force parameters of molecules indicating thereby the naodelindependency of F. as a sensitive QT measuring parameter.
