摘要：

Electrospray ionization (ESI) mass spectra were recorded for a range of substituted isoindoline nitroxides, two isoindoline nitroxide dimers and two piperidinyl nitroxides, In all cases the dominant molecular species arise from oxidation rather than protonation, an unusual process in ESI, Fragment ion spectroscopy was used to establish fragmentation mechanisms for the nitroxides under ESI conditions, Copyright (C) 2000 John Wiley & Sons, Ltd.
