Reaction of SO2 with OH in the atmosphere - RSC Publishing
The OH + SO2 reaction plays a critical role in understanding the oxidation of SO2 in the atmosphere, and its rate constant is critical for clarifying the fate of SO2 in the atmosphere. The rate constant of the OH + SO2 reaction is calculated here by using beyond-CCSDT correlation energy calculations for a be

Kinetics of OH + SO2 + M: temperature-dependent rate coefficients in the fall-off regime and the influence of water vapour. Atmospheric Chemistry and Physics 2022 , 22 (7) , 4969-4984.
rate constants of the OH + SO 2 reaction under atmospheric conditions using canonical variational transition theory with small-curvature tunneling and system-specific quantum RRK theory with a chemical activation mechanism. The present results yield reliable rate constants that remove the discrepancy between experiment and theory.
Oxidation of sulphur compounds in the atmosphere: I. Rate
The reactions of OH radicals with SO2, H2S, thiophenol, and a series of aliphatic thiols (1–5 C-atoms) have been investigated in 201 and 381 reaction chambers at 1 atm total pressure and 300 K using a competitive kinetic technique. Initially, OH radicals were produced by photolysis of CH3ONO/NO mixtures in air.
