The method of quantitative laser induced chemiluminescent kinetic spectroscopy (QLICKS) is developed for the study of chemiluminescence reactions. This method enables us to determine spectral distributions of chemiluminescence rate constants kcl(λ) (photon cm3/particle2 s nm) and total chemiluminescence rate constants kcl (photon cm2/particle2 s). QLICKS is applied to the study of the iodine atom recombination accompanied by radiation according to I(5p5 2P 1 2) + I(5p5 2P 3 2) → (M) I2(B Ou+, υ′) → I2(X Og+, υ″) + hν (i). Iodine atoms are obtained by photolysis of RI = CF3I, CF3CFICF3 at λ = 266 nm. Assuming quantum yields of the I(2P 3 2) and I(2P 1 2) atoms formation equal to 0.1 and 0.9, respectively, the following values of the total chemiluminescence rate constant are determined: ki = (10+10-5, 7.4+7-4 and 3.0+3-1.6) × 10-15 photon cm3/particle2 s for M = He, Ar and CF3CFICF3 respectively. The rate constant of the process 2I(5p5 2P 1 2) → (M) I2(1u) → I2(1g) + hν (ii) is estimated to be kii = (3.5+3.5-1.
