The fragmental behavior of some monocyclic N ‐aryl‐δ‐valerolactams in EI‐MS was studied. Their molecular ion peak, together with some characteristic fragments such as [M‐29] + , [M‐56] +• , [M‐69] + , and [M‐98] + , were always found in a series of N ‐aryl‐δ‐valerolactams in EI‐MS spectra. Furthermore, the mechanism for the interpretation of each fragment is described.
