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.
