Notes

1Spin splitting constant γ0 = +0.6.
2Lifetimes of 6.1 and ~2 ns have been reported Smith and Stella, 1975 for the upper state of the C→A bands and for the 1850 group, respectively. See 3 of O1H.
3Only the 0-11 and 0-12 bands have been observed Carlone and Dalby, 1969.
4Strong many-line spectrum 1900-1700 Å, tentative identification.
5Spin splitting constant γ0 = -0.156.
6See note h of O1H.
7ΔG(3/2) = 357.9 Carlone and Dalby, 1969. Using isotope relations Barrow, 1956 derives ωe = 684, ωexe = 55.7, ωeye = -8.3.
8Spin splitting constant γ < 0.05.
9B1 = 2.445, B2 = 1.947 Carlone and Dalby, 1969.
10D1 = 4.48E-4 Carlone and Dalby, 1969, D2 = 18.9E-4; H0 = -12E-7, H1 = -16E-7 Carlone and Dalby, 1969.
11Franck-Condon factors Felenbok, 1963.
12Te has been corrected for the effects of Y00 on the zero-point energy in both upper and lower state and for a small electronic term ovΣ due to interaction with the 2Π state; see Coxon, 1975.
13The constants represent only v=0...3, Coxon, 1975; Vibrational energy levels and ΔG values up to v=13 are listed in Carlone and Dalby, 1969. Preliminary vibrational constants may be found in Barrow, 1956.
14Spin splitting constants Coxon, 1975: γ0 = +0.1201 [good agreement with Douglas, 1974], γ1 = +0.1170, γ2 = +0.1114.
15In low-pressure flames and discharges the intensity of emission lines originating in v' = 0, 1, 2 decreases rapidly above N' = 29, 26, 17, respectively Broida and Kane, 1953, owing to predissociation by 4Σ- (see 15 of O1H); substantially higher N' values in Palmer and Naegeli, 1968 correspond to the first lines of zero intensity. The lifetime of the v' = 0 rotational levels drops sharply above N' ~ 34 Elmergreen and Smith, 1972, Wilcox, Anderson, et al., 1975. A much stronger predissociation occurs for v = 7...12 causing diffuseness in the B→A bands in low pressure discharges Carlone and Dalby, 1969, Czarny, Felenbok, et al., 1971; asymmetric line shapes in the 0-9 band have been studied by Carlone, 1974 and have been found Carlone, 1975 to contain a Q component because of mixing with the 4Π state that causes the predissociation Czarny, Felenbok, et al., 1971.
16μel(v=0) = 2.16 D Scarl and Dalby, 1971, see note q of O1H. A considerably lower value of 1.72 D was derived by Weinstock and Zare, 1973 from Stark shifts in the location of high-field level crossings and appears to be favored by ab initio calculations [for references see Weinstock and Zare, 1973]. Hfs constants from high-field level crossing experiments in Weinstock and Zare, 1973 [eqQ corrected by Woods and Dixon, 1976 and German, 1976].
17RKR potential functions Coxon, 1975.
18The equilibrium constants refer to the true mechanical Bv values derived by Coxon, 1975 from the effective constants (given in the same paper) for v≤3. Term values for v≤3 Clyne, Coxon, et al., 1973.
19+1.65E-8J3(J+1)3 - 6.0E-13J4(J+1)4 Coxon, 1975; good agreement with D0 and H0 of Douglas, 1974. Coxon, 1975 gives Dv, Hv for v≤2.
20Radiative lifetimes τ(v=0,N=1) = 691 ± 9 ns, τ(v=1,N=1) = 712 ± 10 ns, τ(v=2,N=1) = 736 ± 13 ns German, 1975. Elmergreen and Smith, 1972, Becker and Haaks, 1973, Brophy, Silver, et al., 1974, Wilcox, Anderson, et al., 1975 give somewhat longer lifetimes for low rotational levels in v=0; Hanle effect measurements de Zafra, Marshall, et al., 1971, German, Bergeman, et al., 1973 are slightly lower. Oscillator strengths from high-resolution line absorption: f00 = 0.00096 and f10 = 0.00026 for the rotationless molecule Rouse and Engleman, 1973.

Franck-Condon factors Felenbok, 1963, Coxon, 1975. Vibrational intensity distribution, variation of the transition moment with r, rotational dependence of transition probabilities Crosley and Lengel, 1977.

23Λ-type doubling parameters p0 = +0.1266, q0 = -0.010934; additional constants for v≤3 Coxon, 1975; ab initio calculation Coxon and Hammersley, 1975.
24Term values for v≤3 Clyne, Coxon, et al., 1973.
25D1 = 5.331E-4, D2 = 5.28E-4; H0 = 1.935E-8, H1 = +2.065E-8, H2 = +2.46E-8; L0 = -5.2E-13 Coxon, 1975. For v=0 good agreement with Douglas, 1974.
