Abstract

The behaviour of some aromatic tri‐ and tetraoxo compounds and of their p‐substituted derivatives under electron‐impact has been investigated by means of high and low resolution mass spectrometry, metastable refocusing and deuterium labelling. Some characteristic fragmentation processes observed with these compounds indicate that their molecular ions exist in the enol form. The formation of principal fragment ions is discussed.

## Abstract It is shown that the ‘metastable’ mass spectra of a series of monosubstituted benzenes are consistent with reaction over the lowest available energy surfaces. The non‐occurrence of some qualitatively possible decomposition pathways may therefore be used to place lower limits on the heat
