Abstract
Fragmentation of 2-amino-3-methylpyridine has been investigated by electron impact in the carbon and nitrogen K-shell excitation regions with a comparison to that of 3-methylpyridine. Fragment ions were analyzed with a quadrupole mass spectrometer. Yields of the NCNH 2 + and C 5 H 3 + /C 4 HN + fragment ions characteristically increase at the N 1 s edge when compared to the C Is excitation/ionization and valence ionization. This observation indicates that a valence electron forming the C-N bond in the pyridine ring is preferentially released through an Auger electron emission at the N Is edge. The fragment ions produced via a hydrogen atom shift were observed as well.
