The Formation, Stability and Decomposition of + (X=NH2, SH, OH and Cl) Ions During Hydrogen Chemical Ionization Mass Spectrometry

Article abstract of DOI:10.1002/oms.1210170609

The 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 ⁺ ions are described, and the formation of significant ions is discussed.
