ABSTRACT
The mass spectra of a series of N-Arylα,β-unsaturated γ-lactams (Fig 1), and monocyclic N-Aryl--valerolactams (Fig 2) were studied, respectively. Besides their molecular ion peak, together with their characteristic fragments such as [M-29] +, [M-55] +, [M-82] + and [M-29]+, [M-56] , [M-69]+, and [M-98]+ were found in EI-MS spectra, respectively. Furthermore, based on the exacted mass and chemical compositions of each fragment determined by high-resolution mass spectrometry (HRMS), the forming mechanism for the interpretation of each fragment was rational proposed. This result is expected to be useful information for further identification of N-Aryl α,β-unsaturatedγ-lactams and monocyclic N-Aryl--valerolactams.
