Abstract

Electron impact mass spectra of 65 pyrrolidine‐N‐oxyl derivatives have been assigned on a ‘peak‐to‐subgraph’ basis. On average, 50% of the total ion current is represented by structurally significant fragments associated with the nitroxide group. Secondary fragmentation is, as a rule, of a minor importance (30%), and fragments due to functional groups other than NO· seldom contribute more than 10% of the total ion current An enhanced specificity of fragmentation is observed when one or more of the 2,2, 5,5‐methyl groups is replaced by a longer aliphatic chain or an aromatic group.
