We have studied the association reaction of the CF₂Cl radicals with O₂ in presence of N₂. The infrared multiple photon dissociation (IRMPD) technique with a homemade TEA CO₂ laser was used for the CF₂Cl 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 CF₂O photoproduct was used to measure the disappearance rate of these radicals. A kinetic mechanism is presented to account for the rate of production of CF₂O^*. The CF₂Cl radical association reaction rate with O₂, evidence of a direct channel of photoproduct formation and its reaction rate, and the CF₂O^* collisional deactivation rate have been obtained.
