Consecutive elimination of H2 molecules observed in high-energy electron transfer dissociation (HE-ETD) of protonated amino alcohols
High-energy electron transfer dissociation (HE-ETD) of singly protonated amino alcohols was investigated using charge inversion mass spectrometry with alkali metal targets in which dissociations were induced from the excited neutral intermediates. Consecutive dissociations of three H2 loss and that of H2 and NH3 loss from the charge reduced neutrals were observed. The relative intensities of these dissociation showed the clear dependence on the target alkali metal atoms.
