The rate constant of the reaction between CCl 2 radicals and HCl was experimentally determined. The CCl 2 radicals were obtained by infrared multiphoton dissociation of CDCl 3 . The time dependence of the CCl 2 radicals' concentration in the presence of HCl was determined by laser‐induced fluorescence. The experimental conditions allowed us to associate the decrease in the concentration of radicals to the self‐recombination reaction to form C 2 Cl 4 and to the reaction with HCl to form CHCl 3 . The rate constant for the self‐recombination reaction was determined to be in the high‐pressure regime. The value obtained at 300 K was (5.7 ± 0.1) × 10 −13 cm 3 molecule −1 s −1 , whereas the value of the rate constant measured for the reaction with HCl was (2.7 ± 0.1) × 10 −14 cm 3 molecule −1 s −1 .
