摘要：

Laser flash photolysis of D2O2/RCH(3)/N-2 and Cl2CO/RCH(3)/N-2 mixtures (R = CH3S or H) was coupled with CH3 detection by time-resolved tunable-diode laser absorption spectroscopy to investigate the importance of C-S bond cleavage as an O-2-independent reaction pathway for the atmospherically interesting reactions of OD radicals and Cl atoms with CH3SCH3 at 298 K. Upper limit CH3 yields derived from the data (95% confidence level) are 0.07 for OD + CH3SCH3 and 0.02 for Cl + CH3SCH3.
