✦ Synopsis

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 laser operating on the P(20) 9.6 g line and collisional pumping to the 3~3, ur and v4 states was measured by monitoring the rise time of the fluorescence at 3000 cm-'. The rate constant was found to be 2.2 X 10s set-r tom-'.
