Abstract

We have studied the association reaction of the CF(2)Cl radicals with O(2) in presence of N(2). The infrared multiple photon dissociation (IRMPD) technique with a homemade TEA CO(2) laser was used for the CF(2)Cl radical generation and the vibrational chemiluminiscence technique was set up for the study of the reaction kinetics. The time-resolved IR fluorescence of the vibrationally excited CF(2)O photoproduct was used to measure the disappearance rate of these radicals. A kinetic mechanism is presented to account for the rate of production of CF(2)O(*). The CF(2)Cl radical association reaction rate with O(2), evidence of a direct channel of photoproduct formation and its reaction rate, and the CF(2)O(*) collisional deactivation rate have been obtained.
