The influence of small additions of tripropylamine on vibrational energy relaxation in C02-containing mixtures has been studied cspL-imentally. The rate constant for deactivation of the v3 mode of CO? by tripropybtine molecules has been measured.

โฆ Synopsis
Opto-acoustic techmques have been used to measure vibrational energy relaxation tn methyl halides and their mixtures wth tnert gases Under certain condihons tune-resolved measurements gwe direct evidence of a V-R-T relaxation channel parallel to the V-T relaxation channel Comparison with infrared fluorescence data confirms thus conclusioa

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

## Previous works have reported vibration-vibration and vibration-translation transfer rates in CHJF and CHg F-X mixtures. fn this letter we report the study of the fast V-V transfer rate populating the 3~3, u1 and ~4 states of CHJF. GaseousCHsF was initially exited to the ~3 state by a TEA CO2 la
The rate of vibrational energy transfer from CHsBr&) to HCN&) has been determined to be 75 f 25 rns-' Torr-I. The factors which determine the relative importance of intermolecular vibrational energy transfer pathways will be discuswd.
