Low energy collision induced dissociation (CID) spectra indicate that m/z 173 ions formed by the loss of a halogen atom from diethyl chloro- and bromo-succinate under electron impact are mixtures of O-protonated diethyl maleate (>90percent) and fumarate (+ ion obtained from diethyl iodosuccinate shows that only a small fraction of the + ions are the O-protonated species formed by hydrogen migration.The result of this study demonstrate the potential of low energy CID in the determination of structure (including configuration) of gas phase ions.
