An energetic study of the production of [C 7 H 8 N] + and [C 6 H 7 ] + 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 [C 7 H 8 N] + and [C 6 H 7 ] + ions were detected and kinetic energy released were determined. The results indicate that the [C 7 H 8 N] + 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. [C 6 H 7 ] + ions are believed to be formed at threshold from the two precursors with a protonated benzene structure.
