WebRecently, a ubiquitous autoxidation product of the OH-initiated H-abstraction of DMS, hydroperoxymethyl thioformate (HPMTF), has been detected in the marine environment. The ubiquity of HPMTF and its formation under low RO 2 and NO x environments leads us to reexamine DMS oxidation product yields with a focus on HPTMF oxidation as a potential ... WebDec 7, 2024 · Context: S-methyl thioformate CH 3 SC(O)H is a monosulfur derivative of methyl formate, a relatively abundant component of the interstellar medium (ISM). S-methyl thioformate being, thermodynamically, the most stable isomer, it can be reasonably proposed for detection in the ISM. trialon burton
