Abstract

Photolysis of CF2Br2 at wavelengths shorter than 135 nm leads to the production of electronically excited CF2. At low pressure fluorescence is observed over the range 230-340 nm. Considerable vibrational excitation of the CF2 is evident. The CF2 fluorescence is quenched by H2, D2, CO and CO2 with rate constants of 5.6 × 109, 2.7 × 109, 4 × 1010 and 3.2 × 1010 dm3 mol -1 s-1, respectively.
