Abstract

The laser-photolysis/laser-induced-fluorescence technique has been employed to study the reactions of CS₂OH with O₂, NO, and NO₂ in the presence of He at 26-202 Torr and 298 K. With excess CS₂ and without O₂, NO, and NO₂, a rapid approach of [OH] to equilibrium was observed, indicating reversible formation of a CS₂OH adduct. When O₂, NO, or NO₂ was present at a small concentration, a rapid decrease of [OH] after reaching equilibrium was observed. Analysis of the [OH] temporal profiles yielded the rate coefficients for each reaction. The coefficients are k(CS₂OH+O₂) = (3.1 ± 0.6) × 10^-4, k(CS₂OH+NO) = (7.3 ± 1.8) × 10^-13, and k(CS₂OH+NO₂) = (4.2 ± 1.0) × 10^-11 cm³ molecule^-1 s^-1; the uncertainties represent 95% confidence limits.
