Effect of Collision Partners on Vibrational Relaxation

摘要

The Schwartz, Slawsky, and Herzfeld theory is applied to some previously reported data on substituted methanehyphen;inerthyphen;gas mixtures. It is found that the vibrational relaxation process can be quite adequately explained with this theory and a knowledge of intermolecular force constants. It is also shown that the linear relationship between log(tgr;AB) and mgr;frac12;, which apparently holds for diatomic dispersive gases, breaks down for more complicated molecules.
