Vibrational relaxation in mixtures containing oxygen

Abstract

Theoretical calculations of the rates of the possible vibrational relaxation processes for binary mixtures of O2 with CH4, CD4, C2H4, C2H2, H2O, D2O and HDO are presented, based on the quantum mechanical theory of Schwartz, Slawsky and Herzfeld. These predict mechanisms involving vibration-vibration and vibration-translation energy transfer which are in qualitative agreement with the available experimental data.
