Abstract

Abstract Some different substituted N-methyl-β, β′-diphenyl-diethylamines (I) were investigated mass spectrometrically. The main fragmentations and their genesis are summarized in Scheme 2. The molecular ion generates the major fragmentions a (m/e 148) and b (m/e (147+ X)); c (m/e 105) is formed from a and d (m/e (104+ X)) from b by further decomposition. The logarithms of the ratios of the relative ion intensities a/b, c/a and d/b ...
