• Experimental values of kinetic energy release T, for predissociation processes of diatomic di‐cations N2+ 2, O2+ 2, and NO2 + have been obtained using techniques of ion‐kinetic‐energy spectroscopy on a double‐focusing mass spectrometer. Both unimolecular and collision‐induced processes were studied. As a result, the present data confirm earlier work but include additional transitions not reported previously. Values of T obtained by entirely different technqiues are shown to be consistent with the present work when differences in energy resolution and experimental time window are considered. Attempts to correlate all available information on these diatomic di‐cations (Auger, double‐charge‐transfer and kinetic‐energy loss spectra, as well as appearance energy measurements) are hampered by lack of high‐level a p r i o r i calculations of the potential curves.
