The formation of m / e 165 in the spectrum of benzyl phenyl ketoxime involves the intermediacy of a rearranged 2,3‐diphenyl‐2‐H‐azirine radical ion. 2 H and 13 C labelling of the ketoxime together with 2 H labelling of the azirine has allowed certain proposals to be made concerning the complex processes producing m / e 165 in both spectra. The mode of formation of m / e 167 in the spectrum of benzyl phenyl ketoxime has also been studied.
