description The photochemistry of methyl thioglycolate (MTG), CH<sub>3</sub>OC(O)CH<sub>2</sub>SH, in gas phase and in matrix isolation conditions was studied by means of FTIR spectroscopy, and the influence of the presence of molecular oxygen on the photochemical mechanisms was investigated. The UV–vis broad-band photolysis of MTG in gas phase originates CH<sub>3</sub>OC(O)CH<sub>3</sub> and S<sub>8</sub>, while in matrix conditions the photoproducts are CH<sub>3</sub>OH, H<sub>2</sub>CS, and CO, interacting inside the matrix cage. The photolysis of MTG in the presence of O<sub>2</sub> conducts to the formation of SO<sub>2</sub>, independent of the experimental conditions, being CH<sub>3</sub>OH, HC(O)OH, and CO the other photoproducts for the gas-phase photolysis, and H<sub>2</sub>CO, CH<sub>4</sub>, and CO<sub>2</sub> for the experiments performed in Ar matrix conditions.
