Reaction of the Hydrated Electron with HS

Evidence is presented to show that the hydrated electron reacts with monohydrogen sulfide ion with a rate constant of (3.0 ± 0.4) × 10 7 M −1 s −1 in contrast to an earlier report that this substrate was unreactive. A comparison of the electron reactivity towards hydrogen sulfides and selenides suggests that the reactivity reflects the ability of the substrate to accommodate the electron as opposed to its ability to donate a proton to the electron.
