詳細

詳細

Dimethyl sulfide (DMS) is a biogenic sulfur compound[1] that is released from the ocean to the atmosphere.[2] It forms the main component of the global sulfur cycle.[1][2] The thermal decomposition behavior of dimethyl sulfide in gas phase has been investigated in a static system at 681-723K.[3] The mechanism of its photochemical oxidation in atmosphere has been described.[2] The rate constant of the gas phase reaction between OH radicals and DMS have been determined by relative rate methods and flash photolysis technique.[4] The differential Raman cross section, σ_DMS at different excitation wavelengths has been measured.[1] The adsorption of DMS on activated carbons (ACs) has been reported to take place by hydrogen bonding.[5]
