摘要：

An energetic study of the production of [C7H8N]+ and [C6H7]+ fragment ions from o-toluidine and N-methylaniline is reported. The mechanisms for the formation of the ions are suggested. Metastable peaks associated with the formation and fragmentation of reactive [C7H8N]+ and [C6H7]+ ions were detected and kinetic energy released were determined. The results indicate that the [C7H8N]+ ion is formed at threshold from o-toluidine with an aminotropylium structure whereas for N-methylaniline the ion is formed with an N-phenylmethaniminium structure. [C6H7]+ ions are believed to be formed at threshold from the two precursors with a protonated benzene structure.
