Abstract

Both dimethylsulfoxide (DMSO) and dimethylsulfone (DMSO(2)) are important products in the atmospheric oxidation of DMS. In addition, DMSO and DMSO(2) have recently been measured in the field. They have been identified both in the gas phase and in the aerosol phase as well as in rainwater, but the fate of these compounds in the atmosphere is poorly understood. This study uses a 480 L Teflon coated reaction chamber, equipped with on-line FT-IR and TDL spectroscopy and off-line ion chromatography, to study products, reaction rate constants and mechanisms of the reactions between DMSO or DMSO(2) and OH or NO(3) to clarify the fate of these compounds in the atmosphere.
