Metastable ion studies. VI. The identification of C2H5N+ ion structures from their characteristic kinetic energy releases

Metastable peaks for the fragmentation C 2 H 5 N +• → C 2 H 4 N + + H • have been studied in the first field-free region of a double focussing mass spectrometer. Isomeric structures of C 2 H 5 N +• ions derived from a variety of precursor molecules were characterised by their metastable peak shape and kinetic energy release. The identifications were aided by appropriate deuterium labelling experiments. Four isomeric ionsr [Formula: see …
