The Vibrational-Translational Relaxation of CF₂HCl in Argon

Abstract

We report in this paper results concerning the vibrational-translational (VT) rates of CF₂HCl diluted in Ar as a neutral buffer. The dependence on the buffer concentration and on the initial vibrational energy distribution are obtained by using the 9R(48) and the 9R(34) CO₂ laser lines for the excitation process. The differences observed between the results corresponding to the two lines bear valuable information about the dependence of the VT relaxation process on the specific initial conditions of vibrational excitation.
