General description

Dimethyl sulfide (DMS) is a biogenic sulfur compound that is released from the ocean to the atmosphere. It forms the main component of the global sulfur cycle. The thermal decomposition behavior of dimethyl sulfide in gas phase has been investigated in a static system at 681-723K. The mechanism of its photochemical oxidation in atmosphere has been described. The rate constant of the gas phase reaction between OH radicals and DMS have been determined by relative rate methods and flash photolysis technique. The differential Raman cross section, σDMS at different excitation wavelengths has been measured. The adsorption of DMS on activated carbons (ACs) has been reported to take place by hydrogen bonding.
