The main fragmentation routes of eighteen title compounds and of three 5-chloro derivatives have been investigated with the aid of linked scan (B/E = constant) spectrometry, accurate mass measurements and deuterium labelling.

Abstract
The positive‐ion electron impact ionization mass spectra of eight substituted 3‐nitropyrroles were examined. The major fragment ions arise by ortho interactions between the 3‐nitro group and the 2‐methyl or 2‐aryl group.

## Abstract The electron impact ionization mass spectra of dipyrido [1,2‐__a__:4,3‐__d__]pyrimidinones are strongly influenced by the degree of aromaticity of the fused rings. The molecular ions of the compounds are fairly stable. The main routes of fragmentation involve formation of the [M – H]^+^
