Notes:
Thermal diffusion factors were measured for several isotopically substituted pairs of carbon disulfide molecules. The effect of a unit mass increment at the carbon position in the molecule was found to be substantially less than the effect of a unit mass substitution at one of the sulfur positions. The results were represented within experimental accuracy by αTij=2.20 (mi−mj)/(mi+mj ) +1.67(Ii−Ij)/ (Ii+Ij), where αTij is the isotopic thermal diffusion factor, mi and mj are the molecular masses, and Ii and Ij are the second moments.
