✦ Synopsis


Apparently competing cleavage and rearrangement reactions in a series of molecular ions have been studied by ionization and appearance potential methods, and by determination of the electron energy dependence of both normal and metastable daughter ion peak intensities. The processes investigated were ,H,] in n-butylbenzoate. The results are interpreted in terms of k us. E curves with very different frequency factors for the two reaction types. Appearance potentials of metastable ions for the rearrangement reactions have also been measured.

## Abstract It has been shown by exact mass measurements and collision‐induced dissociation mass‐analysed ion kinetic energy spectra that the structure of the __m__/__z__ 124 ion observed in the mass spectra of __N__‐(4‐methoxyphenyl)thiophene‐2‐carboxamide, __N__‐(4‐methoxyphenyl)thiophene‐3‐carbo
