2.68 + 0.10 eV, the largest value by far for the kinetic energy release (KER) in the decomposition of metastable, singly charged ions was detected by mass spectrometry for the fragmentation of HONF + . Thus, the exceptionally large KER predicted by a theoretical analysis of the potential energy surface (calculated energy profile shown on the right) was also confirmed experimentally.
