โฆ Synopsis
Rate constants for the reactions of OH radicals and C1 atoms with diethyl sulfide (DES), din-propyl sulfide (DPS), and di-n-butyl sulfide (DBS) have been determined at 295 ? 3 K and a total pressure of 1 atm. Hydroxyl radical rate data was obtained using the absolute technique of pulse radiolysis combined with kinetic spectroscopy. The chlorine atom rate constants were measured using a conventional photolytic relative rate method. The rate constant for the reaction of C1 atoms with dimethyl sulfide (DMS) was also determined. The following rate constants were obtained:
k(C1 + DES) = (44.1 5 4) X 1 0 . ' ' cm3 molecule-'s-' k(C1 + DPS) = (51.8 5 41 x lo-" cm3 molecuIe-'s-' k(C1 + DBS) = (64.6 5 2) X lo-" cm3 molecule-' s-l

Rate constants for the reactions of C1 atoms and OH radicals with haloalkanes were measured using the relative rate technique. From these values the atmospheric lifetimes of the organics with respect to C1 atoms and OH radicals were calculated. C1 atoms were produced by the photolysis of chlorine ga
The kinetics of the reaction of OH radicals with methyl, n-propyl, and n-butyl nitrite OH + RON0products have been studied in a discharge flow system under pseudo first-order conditions. The OH radicals were generated by the reaction of H atoms with NO2 and the concentration of OH, monitored by reso
