Fast atom bombardment, frit fast atom bombardment and electrospray ionization mass spectrometric study of organic salts C2+ 2X: Matrix and anion effects

Abstract
The fast atom bombardment (FAB), frit‐FAB and electrospray ionization mass spectra of bis‐ammonium salts, C2+ 2X, were compared. The most informative spectra were the FAB mass spectra with m‐nitrobenzyl alcohol as matrix and the Frit‐FAB mass spectra. The nucleophilic character of the iodine anion was established.
