Abstract

Time-resolved LMR is employed to study the deactivation Cl(²P_{1 2}) generated by pulsed photolysis of ICl at 530 nm. The yield of excited chlorine atoms Cl(²P_{1 2}) is found to be 55 ± 5%. The Cl^{{black star}} quenching rate constants are: (1.7 ± 0.4) × 10^-13, (7.2 ± 2.0)×10^-13, ≤ 1.5 × 10^-14 cm³ s in O₂, Cl₂ and Ar, respectively (± 2σ). The Cl^{{black star}} deactivation (quenching + reaction) rate constant in ICl is (3.3 ± 0.5)×10^-13 cm³ s, which is 24 times lower than the rate constant for the reaction Cl (²P_{3 2})+ICl→I+Cl₂. (All at 295 ± 5 K.).
