Ionization and Dissociation of Some Pyromellitimides under Electron-Impact.

Abstract

The mass spectra of twenty three pyromellitimides are reported and discussed. Proposed ion structures are, in most cases, substantiated by precise mass measurement. All compounds examined exhibit molecular-ions and peaks at m/e 102. Ions formed by the loss of carbon dioxide from the molecular-ions, although abundant in some cases, are not common to all the spectra. (Author)
