Kinetics of the decomposition of CF 3 CF 2 Cl at 50 torr by a cw CO 2 laser have been studied over a range of laser frequencies extending 36 cm −1 below an absorption bandcenter at 980 cm −1 . At constant translational temperature, the change in the rate constant with laser frequency is a factor of 100, comparable to the effect previously observed in CF 2 ClCF 2 Cl. Arrhenius plots show an activation energy of 86.2 kcal/mole, independent of frequency.
