Abstract

The time-resolved tunable diode laser detection of CF₃ radicals formed by infrared multiphoton dissociation of (CF₃)₂CO is reported. Knowledge of the linestrength of the ^rR₁₆(20) CF₃ absorption linc at 1264.739 cm^-1 allows the calculation of a rate constant for recombination of CF₃ radicals following (CF₃) ₂CO photolysis. This rate constant has a value of (2.2± 0. 5) × 10^-12 cm³ molecule^-1 s^t̄1 in (CH₃)₂CO at 600 mTorr and room temperature.
