Title: Methylsulfonyl and methoxysulfinyl radicals and cations in the gas phase. A variable-time and photoexcitation neutralization-reionization mass spectrometric and ab initio/RRKM study

The oxidation cascade reactions converting the so-called reduced sulfur compounds (H{sub 2}S, dimethyl sulfide, dimethyl disulfide, etc.) to oxidized sulfur compounds (SO{sub 2}, sulfuric acid, and methanesulfonic acid) in the troposphere involve several reaction intermediates. The concentrations of these intermediates in the troposphere are very small, which makes direct observation and characterization difficult. The title radicals were produced by femtosecond collisional electron transfer in the gas phase and studied by the methods of variable-time neutralization-reionization mass spectrometry combined with fast-beam laser photoexcitation and G2(MP2) ab initio/RRKM calculations.
