- Energy selected and mass‐resolved electron‐ion coincidence spectra of heavy water have been recorded for ionization energies from 18 to 35 eV. Dissociation from the B2B2 state produces both O+ and D2+ at energies near their thermodynamic thresholds in addition to the known products D+ and OD+. Relative yields of O+, OD+ and D+ in the B2B2 state breakdown diagram are modulated by the vibrational structure of the B‐state population, implying incomplete energy equilibration before fragmentation. Decay from the C‐state produces OD+ in addition to the known O+ and D+. The fragment kinetic energies suggest that O+ and D+ from the C state are products of full atomization of the molecule.
