Abstract

Laser flash photolysis has been used to study the mechanism of the OH initiated oxidation of dimethylsulfide (DMS) and its deuterated analog. Pulsed laser-induced fluorescence was employed to monitor OH decays and tunable diode laser absorption spectroscopy was used to monitor yields of HOD. The formation of an OH-DMS-d6 adduct was directly observed and its binding energy determined. The rate coefficient for the reaction of the adduct with oxygen was determined. Evidence for production of HO2 in the reaction of the adduct with oxygen was obtained. Direct observation of the HOD product of the reaction of OD with DMS in high yield supports H atom abstraction as the dominant reaction pathway in the absence of oxygen. -from Authors
