Abstract: 

The atmospherically highly relevant methylsulfonyl radical (CH₃SO₂^•)
was generated by high-vacuum flash pyrolysis (HVFP) of
allylmethylsulfone and isolated in an argon matrix at 10 K; the allyl
radical formed as the cofragment. Upon thermolysis, the methylsulfonyl
radical undergoes partial decomposition, leading to substantial amounts
of sulfur dioxide in the matrix. The title compound was characterized
through the assignment of eight fundamental IR bands of its CD₃ and ¹³CH₃
isotopologues and the excellent agreement with the
B3LYP/6-311+G(3df,3pd) computed harmonic vibrational frequencies. The
two most intense absorptions were found at 1267.1 and 1067.6 cm^–1. In extension of this study S-methyl
methanethiosulfonate was found to be another suitable, although less
efficient, precursor for the gas-phase generation of the methylsulfonyl
radical.
