Abstract

Previous works have reported vibration-vibration and vibration-translation transfer rates in CH3F and CH3FX mixtures. In this letter we report the study of the fast VV transfer rate populating the 3ν3, ν1 and ν4 states of CH3F. Gaseous CH3F was initially excited to the ν3 state by a TEA CO2 laser operating on the P(20 9.6 μ line and collisional pumping to the 3ν3, ν1 and ν4 states was measured by monitoring the rise time of the fluorescence at 300 cm-1. The rate constant was found to be 2.2 × 105 sec-1 torr-1.
