Abstract
Products and mechanisms have been investigated for the reactions between dimethylsulfide (DMS) and dimethylsulfoxide (DMSO) and the hydroxyl radical (OH) in the presence of NOx. All of the experiments were performed in a 480 L reaction chamber, applying Fourier transform infrared spectroscopy (FT-IR) and ion chromatography as the analytical techniques. In addition to the sulfur containing products that are known to be produced from the gas phase reaction between DMS and OH (SO2, dimethylsulfone, methylsulfonyl peroxynitrate, methanesulfonic acid, H2SO4), DMSO and methanesulfinic acid (CH3S(O)OH) were also observed as products. Only SO2, DMSO(2) and methylsulfonyl peroxynitrate were found assulfur containing products in the reaction between DMSO and OH. Basedon these new results we propose a mechanism for the atmospheric oxidation of DMS and DMSO by OH radical.
