Reactions of the HnS+ ions (n = 0 to 3) with several molecular gases at thermal energies

Abstract
The rate coefficients and product ion distributions have been determined at room temperature for the reactions of the ions HnS+ (n = 0 to 3) with several diatomic and polyatomic gases. The reactions generally proceed at or near the collisional limit, often generating multiple products. Charge transfer, proton transfer, and atom abstraction, in some cases occurring in parallel, are evident within the data array, emphasizing the complexity of these reactions. The results obtained for the near‐thermoneutral reactions of S+ and HS+ with H2S have provided values for the recombination energies of HS+ and H2S+ ions which, within the limitations of the assumptions made, are more closely defined than the previous values.
