Vibrational Energy Transfer in Thermal Unimolecular Systems by the Diffusion Cloud Method. Cyclopropane.

Abstract

The present paper presents data on the relative collision efficiencies of cyclopropane in N2, CO2, H2, and He bath gases using the diffusion cloud technique. Temperature dependence of the rate has also been measured between 975 - 1175 K. Since the diffusion constants increase at higher temperatures, it was necessary to extend the mathematical treatment presented in the earlier paper. A model given by Nevrovskii which employs reflections at the wall and a flat velocity (plug flow) profile has been considered. Efforts have been made to extend the treatment to the case of a laminar (parabolic) flow contour, with only partial success. However, the present results serve to illustrate the usefulness of this method for the study of unimolecular systems.
