Abstract

The N-acetyl-p-nitrobenzyl esters of these compounds were used. m/e 136 represents the p- nitrobenzyl group, m/e 42 represents CH2C0, and m/e 46 represents NOz-: all peaks greater than 5% of the respective base peaks are shown. ionization efficiency (IE) curves. The IE curve for the carboxylate anion of N-acetylalanine (m/e 130) is shown in Figure 1. This curve exhibited a dissociative resonance capture maximum at 2.9 eV which was the same as ...
