## 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

β¦ Synopsis
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.

The rate of vibration to vibration energy transfer from CH3F excited to ~3 = 1 at 1050 cm-l to the nitric oxide and carbon monoxide fust vibrationally excited states at 1875 cm-1 and 2143 cm-t, respectively, has been measured. The V-V crossover rate was determined to be 5.5 -C 0.5 msec-r torr-' for
The vibration-vibration ene=y transfer of HCI gas initially excited to the tirst vibrational level is measured by monitoring the fluorescence of the 2-1 transition. The rate constant for the process is found to be 0.9 x IO5 secwl tom-'.
ti general formula of the probability of vibrational transitions in diatomic molecules is formulated with specific consideration of vibration-vibration energy transfer for nonresonant cases. An application to HZ-H2 collisions shows an excellent agreement of the present formulation with exact quantum
