Notes

1Vertical transition.
2K state of N2 (removal of one K electron)
3Consisting of a v" progression (v"= 0...5).
4Observed X-ray emission line leading to X 2Sigmag+(v=0); the value predicted from the K limit and I.P.(N2) is 393.9 eV. The X-ray line has a shoulder at 394.17 eV probably corresponding to v"=1.
5Repulsive state corresponding to removal of a 2sigmag electron and dissociating into N(4S) + N+(2s2p3 3P), observed in photoelectron and photoion spectra with maximum at 39.8 and limit at 37.86 eV.
6Different constants are derived by Joshi, 1966 who assumes that the levels v=0,1,2 are perturbed and therefore does not include them in the evaluation: he gives Te = 64562.93 cm-1 Joshi, 1966.
7Vibrational numbering confirmed by 14N-15N isotope shifts Baer and Miescher, 1953, Namioka, Yoshino, et al., 1963, Joshi, 1966, 2. Additional vibrational levels (to v'=17) observed by Asbrink and Fridh, 1974 in the photoelectron spectrum.
8Bv(v=1)= 1.5096, Bv(v=2)= 1.5035, Bv(v=3)= 1.4970, Bv(v=4)= 1.4898, Bv(v=5)= 1.4804, Bv(v=6)= 1.4700. The shape of the Bv curve is anomalous; meaningful equilibrium constants have not been determined. Spin doubling partially resolved for high N values Carroll, 1959.
9In a discharge through He+N2 the v'=3 bands are strongly enhanced. It has been suggested Douglas, 1952 that this enhancement is due to inverse predissociation, i.e. N(4S) + N+(3P) rarrow N2+(C 2Sigmau+): see also Carroll, 1959. Direct predissociation, i.e. the production of N+ ions, has been observed mass- spectrometrically Wankenne and Momigny, 1971, Wankenne, Bolduc, et al., 1975: see also Fournier, Ozenne, et al., 1970, Fournier, van de Runstraat, et al., 1971. According to Wankenne and Momigny, 1971 the "metastable" ion N2+(C 2Sigmau+) has a lifetime of 0.8 mus before radiationless decomposition; see, however, van de Runstraat, de Heer, et al., 1974 and 10. The question which state causes the predissociation has been the subject of much discussion Lorquet and Lorquet, 1974, Tellinghuisen and Albritton, 1975, Roche and Lefebvre-Brion, 1975 following the discovery of a large isotope effect on this predissociation Govers, van de Runstraat, et al., 1973, Govers, Fehsenfeld, et al., 1974, van de Runstraat, de Heer, et al., 1974, Govers, van de Runstraat, et al., 1975. See also Fournier, Govers, et al., 1972. Another predissociation limit at 26.70 eV above N2(X 1Sigmag+,v=0) and corresponding to 2D0 + 3P has been observed by Asbrink and Fridh, 1974.
10Radiative lifetime of the nonpredissociated levels tau(vleq2) = 0.09 mus Fournier, van de Runstraat, et al., 1971.
11A = -16.5.
12Vibrational numbering confirmed by 14N-15N isotope shifts Namioka, Yoshino, et al., 1963.
13The identification of this quartet-doublet transition by d'Incan and Topouzkhanian, 1975 has been questioned by Dressler, 1976 who considers it as the first negative system of 14N15N+.
14omegaeze = -0.0495; these constants, derived from omega0, omega0x0, ... of Coster and Brons, 1931, represent the unperturbed vibrational levels only to v=10: for v>10 the DeltaG curve shows a positive curvature. Levels observed up to v=29 Douglas, 1952.

19Lifetime tau(v=0) = 60.5 ns Dotchin and Chupp, 1973, Smith, Read, et al., 1975, see Dotchin and Chupp, 1973, Smith, Read, et al., 1975 and earlier work quoted by them. Perturbed rotational levels (e.g. v=1, N=13,14) have lifetimes up to tau(v=1,N=13,14)= 95 ns Dufayard, Negre, et al., 1974. f00= 0.019 Nicholls, 1963; the electronic f value at the wavelength of the 0-1 band is f= 0.034 Wray and Connolly, 1965.
20Observed in absorption in flash discharges Herzberg, 1968; laser-induced fluorescence Engelking and Smith, 1975. From intensity measurements Lee and Judge, 1973 conclude that the electronic transition moment is nearly independent of r; see, however, Nicholls, 1963, Kiselyovskii and Shimanovich, 1968, Brown and Landshoff, 1971.
