CCl2 free radicals were produced by dc discharge of CCl4(in Ar). Ground electronic state CCl2 radical was electronically excited to A 1B1 (0,4,0) state with Nd:YAG laser pumped dye laser at 541.52 nm. Experimental quenching data of CCl2 (A 1B1 and a 3B1) by O2,N2,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 kA and ka were first time acquired by analyzing and dealing with these data by using a threelevelmodel proposed by us.
