Reduced organic sulphur compounds have been estimated to account for approximately 25% of the total global gaseous sulphur budget. The species play a vital role in the atmospheric sulphur cycle and it is important to understand their fate in the troposphere. The reduced organic sulphur compounds are mainly emitted from the sea surface, although anthropogenic emissions might also be of importance. In the present study the products, CH(3)CH(2)SO(3)H, SO(2), H(2)SO(4), CH(3)CHO, and CH(3)CH(2)ONO(2) were identified and quantified in the reaction of the three compounds, CH(3)CH(2)SH, (CH(3)CH(2))(2)S, and (CH(3)CH(2))(2)S(2). The products were CH(3)CH(2)SO(3)H, CH(3)SO(3)H, SO(2), H(2)SO(4), CH(3)CHO, and CH(2)O in the reaction of CH(3)CH(2)SCH(3). On the basis of identified reaction products and intermediates observed in the infrared spectra, mechanisms are proposed for the reactions between the NO(3) radical and the four reduced organic sulphur compounds.
