A laser photolysis/transient absorption technique has been employed to investigate the photolysis kinetics of aqueous CS2-HONO solutions at 355 nm. Spectral analysis shows that CS2OH will react with HONO to form CS2OH-HONO. Temperature dependent rate coefficients for the reaction are reported for the first time. The following Arrhenius expressions adequately summarize the kinetic data obtained over the temperature range 273-313 K (units are L·mol-1·s-1): ln k = (31.6 ± 0.6)-{(4.1 ± 0.2) ×103/T}, and the activation energy in unit of kJ·mol-1 is 32.47 with the temperature accuracy 0.2 K.

The following Arrhenius formulas adequately summarize the kinetic data obtained over the temperature range 273-313 K (units are L · mol-1 · s-1): ln k = (31.6 ± 0.6) - {(4.1 ± 0.2 ) × 103 / T}, and the activation energy in unit of kJ · mol-1 is 32.47 with the temperature accuracy 0.2 K.
