• CCl2 (A B-1(1,) a B-3(1))
• kinetics
• quenching rate constant
• three-level model

CCl2 free radicals were produced by dc discharge Of CCl4 (in Ar). Ground electronic state CCl2 radical was electronically excited to A B-1(1) (0, 4, 0) state with Nd: YAG laser pumped dye laser at 541. 52 nm. Experimental quenching data Of CCl2 (A B-1(1), and a B-3(1)) by O-2, N-2, NO, CO2, CS2, H2O, SO2 and SF6 were obtained by observing time resolved fluorescence from the excited CCl2 radicals, which showed a superposition of two exponential decay components. The state-resolved rate constants k(A) and k(a). were first time acquired by analyzing and dealing with these data by using a three-level-model proposed by us.
