Abstract
Energies and potential surface characteristics are assigned to the first eight excited states of the water molecule. This assignment is shown to be consistent with all data from optical spectra, electron scattering, rotational distributions of the OH fragment in photodissociation and associated data, and with semi‐empirical INDO calculations. Energies and potential surfaces are given for the lowest resonant states of H2O−. These are consistent within the explainable error of the INDO calculations, as well as with the data on dissociative attachment and associative detachment in which H2O− is an intemediate for species. Assignment‐confirming experiments are suggested.
