The relevant peaks of the H 2 chemical ionization mass spectra of C 1 C 4 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.
