Does the HO2 radical react with H2S,CH3SH,and CH3SCH3?
Authors:A. Mellouki  A. R. Ravishankara
Abstract:
The kinetics of the title reactions were investigated in a discharge flow tube by using laser magnetic resonance detection of HO2. The upper limits for the bimolecular rate constants for the reactions of HO2 with H2S (k1), CH3SH (k2), and CH3SCH3 (k3) are <3 × 10?15, <4 × 10?15, and <5 × 10?15 cm3 molecule?1 s?1, respectively, at 298 K. Our upper limit for k1 is three orders of magnitude lower than the previously reported value. Measurements at higher temperatures also yield similar upper limits. Our results suggest that HO2 is not an important oxidant for these reduced compounds in the atmosphere. © 1994 John Wiley & Sons, Inc.
