title: Electron induced dissociation (EID) tandem mass spectrometry of octaethylporphyrin and its iron(III) complex.
abstract: EID tandem mass spectrometry of singly-charged electrosprayed ions of octaethylporphyrin (OEP) and its iron(III) complex results in ionisation to give doubly-charged precursor and fragment ions. Singly-charged fragments are also observed. EID fragmentation differs significantly to that observed in electron ionisation mass spectrometry.
