1. introduction
The study of vlbratlonal relazzatlon and energy trans-
fer processes in rnatrlv Isolated molecules has blossom-
ed m the past few years. Informatron now eusts on
the behavror of a number of vrbratronally and electron-
really ehcrted matrix isolated specres [ I] _One such
system is CH, F [I?].
Vrbratlonal energy transfer m CH,F isolated in
rare gas matrices has prevrously been studred by a
double resonance method where v3, the C-F stretchmg
mode, was pumped by a pulsed CO, laser and the trme
