Gas phase carboxylate anions have been efficiently generated from the p ‐nitrobenzyl esters of nine fatty acids ranging in size from C 6 to C 22 . The process involves the dissociative resonance capture of 2.9 eV electrons by the derivatives. The procedure is specific and gives the carboxylate anions as the base peak in all but two of the derivatives. The technique gives extremely simple spectra, with little additional fragmentation and no rearrangement ions.
