## Abstract The electron‐impact induced fragmentation of twenty 3‐alkyl‐1‐phenyl‐Δ^2^‐1,2,4‐triazolin‐5‐ones, three 1‐phenyl‐1,2,4‐triazolin‐3,5‐diones and ten 2‐alkyl‐4‐phenyloxadiazolin‐5‐ones has been studied by conventional mass spectrometry. The major cleavages take place in the 1‐phenyl‐Δ^2^‐
