Kinetic Energy Release and Fragmentation Pattern of Substituted Anilines after Collisional Activation

摘要

fragmentation of diethylamino sidegroup depending on substituents on the aromatic system. intensity of additional fragments increasing with increasing number of methyl groups. collisional activation leads to more fragmentation reactions. hydrogen from methyl group takes part in fragmentation of diethylamino. sidegroup supported by deuterium and ~(13)C labelling KER values indicate different fragmentation mechanisms.
