Popis: The spectra of benzyl phenyl ketone derivatives contain ions at m/e 165 (C 13 H 9 ) which are produced by skeletal-rearrangement processes. The rearrangement peak is most pronounced in the spectrum of the oxime of benzyl phenyl ketone where it arises mainly from an M-H 2 O species. Deuterium labelling studies and metastable characteristics are consistent with the M - 18 species having the properties of a 2.3-diphenyl-2-H-azirine molecular ion.
