The behaviour under electron impact of two series of isomeric cyclopentane‐ and cyclohexane‐1, 2‐ and ‐1, 3‐dicarboxylic acid dipiperidides was studied. Diagnostic fragmentation pathways were found to differentiate the isomeric diamides. Additional evidence was obtained from the metastable transitions.
