✦ Synopsis

The mass spectra of the alkyl cyanides up to n-pentyl cyanide were studied. Using metastable ion transitions, appearance potentials and deuterium labelling, the fragmentation patterns, spectral characteristics and trends for this series can be given. The investigation of labelled compounds demonstrates the specificity of rearrangement and normal decomposition processes. Alkyl ions in nitriles are produced by simple cleavage of the carbon-carbon bond, while ions of the type [Malkyl]+, which at the first sight could originate in the same way, are presumably formed via cyclic intermediates and are in fact rearrangement ions.

The modes of fragmentation of perchlorylbenzene (C6H6C10s) and its perdeutero derivative under electron impact are reported and discussed. The occurrence of the [C,H,O]and [C,H,O]+ ions is accounted for in terms of a novel phenyl migration from chlorine to oxygen.

## Abstract Studies of both high and low resolution spectra, and of metastable decompositions occurring in both the first and second field‐free regions of the mass spectrometer have led to a postulated scheme for the fragmentation of acridine under electron‐impact. There is no specific loss of labe
