主 题:CS2OH CS2OH-HONO activation energy laser photolysis/transient absorption.
摘 要: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): In k = (31.6±0.6)-{(4.1±0.2)×10^3/T}, and the activation energy in unit of *** is 32.47 with the temperature accuracy 0.2 K.
