Single-collision chemiluminescent reactions of ozone with hydrogen sulfide and methyl mercaptan

Kinetics and mechanisms of the gas-phase reactions of ozone with organic compounds under atmospheric conditions

“…Although there are no kinetic data available for the reactions of 03 with mercaptans, Glinski et al 134,135 have shown that reaction must occur, since chemiluminescence ascribed to S02 phosphorescence or fluorescence was observed when 03 reacted with CH3SH under single-collision conditions.135 However, in view of the fact that the room temperature rate constant for the reaction of 03 with H2S is less than 2 x 10"2°cm3 molecule'1 s"1,136 and because of the low rate constants for the organic sulfides in Table XI, the rate constants for the reaction of 03 with the mercaptans are also probably too low for these reactions to be of any importance under atmospheric conditions. It is not clear whether N20 is also a product of this Rate constants have been obtained for only tetramethyl-and tetraethyllead,137,138 and these data are given in Table XII.…”

Chemiluminescence from the reactions of ozone with sulphur compounds

“…However, no bands due to triplet S02(3B,) were observed in these reactions as reported by Halstead and Thrush (3) in the chemiluminescent emission from reaction [I]. Recently, Glinski et al (4,5 ) have reexamined the reactions of O, with CH3SH and H2S under beam-gas conditions and shown that the vibrationally resolved phosphorescent spectra are due to first triplet excited state of SO2.…”

The gas-phase oxidation of organic sulfur compounds

“…Becker et al [Ill briefly examined the chemiluminescence from the reactions of 03 with CH3SCH 3 and (CH3S) 2, Arora and Chatha [12] observed emission from electronically excited SO 2 produced in the gas-phase reaction of 03 with thiophene, diallyl sulfide, diallyl disulfide, CH3SCH 3, (CH3S) 2, and thiophenol. Glinski et al [13,14] have observed emission from the reaction of 03 with CH3SH ,andGlinski and Dixon [15] observed emission from the reactions of 03 with (CH3S) 2 and (CH3)2S0. In all cases the chemiluminescence resembled that from the SO + 03 reaction, and the investigators concluded that the reactions produced SO as a precursor to the chemiluminescence.…”
