The method of time-resolved laser magnetic resonance (LMR) has been employed to detect spin-orbital excited chlorine Cl*(≡Cl(2P1/2)) atoms at room temperature. The rate constants for the deactivation of Cl× 10–11 cm3 /molecule*s ,± 2σ s by SOCl2 (0.62±0.2), CCl3H (18±5), C2H4 (1.5±0.4) and NO2 (1.5±0.4) are reported. The unknown in literature rate constant for the thermo-neutral reaction of ground state Cl(2P3/2) atoms with SOCl2 were measured. The relative quantum yield of Cl* in photodissociation of SOCl2 is determined to be 0.52 ± 0.03.

Keywords:
