| Abstract: | Infrared diode laser spectroscopy was applied to the detection of CF2 carbene produced by CO2-laser-induced dissociation of CHClF2. Time-resolved spectra of CF2 in several rotation-vibration states were observed. The initial concentration of CF2 was estimated to be 5 × 1016 molecules cm−1 from an analysis of the time-resolved spectra. The effect of Ar diluent on the time variation of the concentration of CF2 is discussed. |
