Energy transfer processes in CH3F have been reinvestigated under high excitation conditions with and without added rare gas via a mathematical model developed as a consequence of studies under low excitation--The model can be used to describe energy transfer under high escitation conditions with the

Infrared double resonance and saturation techniques have both been used to measure the V-T relaxation of the 19 mode of CH3F in dilute solution in the cryogenic liquid hosts 02 and Ar. With the former technique, a relaxation time of 375 + 35 ns is found in liquid 02 while in liquid Ar the relaxation
