Some novel eliminations of neutral fragments from ions in mass spectrometry. Part I. Alkyl and aryl sulphonylhydrazones

Abstract

The unusual elimination as molecules of part of the internal structure of a sequence of atoms in ions produced in mass spectrometry is described. Simple model compounds from which hydrogen cyanide, nitriles, and di-imide are eliminated have been examined. The loss of an internal segment of an ion with the formation of a new sequence of atoms has indicated some considered limitations in the techniques of element mapping.
