  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.

  A flowing-afterglow apparatus coupled with a low pressure chamber has been used to measure product ion distributions and rate constants in the charge-transfer reactions of Ar+ with CHnF4−n (n=1–3) at thermal energy. Near-resonant dissociative charge transfer followed by loss of H and/or F are major product channels observed. In the Ar+/CH3F reaction, CHF+ and CH2+ ions, which are either absent or very weak in He(i) photoionization, are also found as minor products. The product ion distributions suggest that the Ar+/CHnF4−n (n=1–3) reactions proceed dominantly through near-resonant charge transfer. The total rate constants are 1.7±0.6, 1.9±0.7, and 2.0±0.6×10−9 cm3 s−1 for CH3F, CH2F2, and CHF3, respectively. These values are in reasonable agreement with those predicted from the average dipole orientation (ADO) theory, being independent of the existence of ionic states with favorable Franck–Condon factors for ionization.
