摘要

The reaction of nitrate radical with dimethyl sulfide was studied with cavity ring-down spectroscopy in 20200 Torr of N-2 diluent in the temperature range of 283 - 318 K. The rate constant for this reaction, k(1), is found to be temperature dependent and pressure independent: k(1) = 4.5(-2.8)(+4.0) x 10(-13) exp[(310 +/- 220)/T]cm(3) molecule(-1) s(-1). The uncertainties are two standard deviations from regression analyses. The present rate constants are in good agreement with those reported by Daykin and Wine (Int. J. Chem. Kinet. 1990, 22, 1083) and may be used in the atmospheric model calculation. Theoretical calculations were carried out to verify the existence of an intermediate complex.
