  The formation, stability and decomposition of [RXH]+ (XNH2, SH, OH and Cl) ions during hydrogen chemical ionization mass spectrometry

  摘要：

  AbstractThe relevant peaks of the H2 chemical ionization mass spectra of C1C4 amines, thiols, alcohols and chloroalkanes are reported. The stability of alkylonium ions is discussed on the basis of the proton affinity of the starting neutrals, the substituent alkyl group, and the functional group. The main decomposition paths of [M+1]+ ions are described, and the formation of significant ions is discussed.

• Reactions of the H_<i>n</i>S⁺ ions (<i>n</i> = 0 to 3) with several molecular gases at thermal energies

  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.
