THE VIBRATIONAL-TRANSLATIONAL RELAXATION OF CF2HCL IN ARGON

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