Abstract

The V-T/R relaxation time of CDF3 was measured studying the laser-induced infrared fluorescence emitted by vibrationally excited CDF3. Following excitation by the 10R(12) line of a TEA CO2 laser infrared fluorescence has been detected without spectral resolution in the 1100–700 cm−1 range. A decay rate of 28.8 ms−1 Torr−1 was obtained for pure CDF3 when it is excited with a fluence of 390 mJ/cm2. Measurements have also been made in the presence of different bath gases (He, Ne, Ar, Xe, and CHF3).
