The nature of the state (or states) involved in the production of N(2D) + O- by dissociative electron attachmnet (7-12 eV) has been discussed by van Brunt and Kieffer, 1974; see also Thulstrup, Thulstrup, et al., 1974.

1Symmetries assigned on the basis of theoretical calculations Lefebvre-Brion, 1973. The states consist of two Rydberg electrons temporarily bound to the NO+ X 1Σ+ core.
2Short vibrational progressions of resonances in teh electron transmission current Sanche and Schulz, 1971 predicted widths range from 1 to 25 meV Pearson and Lefebvre-Brion, 1976.
3From the analysis Tronc, Huetz, et al., 1975, Teillet-Billy and Fiquet-Fayard, 1977 of electron scattering data Spence and Schulz, 1971, Schulz, 1973, Burrow, 1974, Zecca, Lazzizzera, et al., 1974. For the ground state Siegel, Celotta, et al., 1972 estimate ωe ~1470 cm-1 Siegel, Celotta, et al., 1972, see 4.
4Franck-Condon factor analysis of the photodetachment spectrum Siegel, Celotta, et al., 1972. The analysis of electron scattering data Teillet-Billy and Fiquet-Fayard, 1977 leads to re = 1.267 Å Teillet-Billy and Fiquet-Fayard, 1977.
