Kinetics, Mechanism and Product Yields in the Atmospheric Oxidation of Dimethylsulfide

Abstract

Dimethylsulfide (DMS, CH3SCH3) produced by phytoplankton degredation is thought to be the major source of the sulfate and methanesulfonate aerosol found in the marine boundary layer. An understanding of the mechanism of formation of these aerosols is critical in evaluating the factors which control visibility in the marine boundary layer. The primary objective of this research effort is to determine the detailed mechanism of, and final product yields from, the OH initiated gas phase oxidation of DMS.
