Notes
| 1 | All lines diffuse; predissociation. |
| 2 | All observed vibrational levels of B 2Σ show perturbations by A 2Π levels with v ≥ l. The rotational constants in Stenvinkel, 1936 are satisfactorily reproduced by Bv = 3.304 - 0.033(v+1/2) + 0.00060(v+1/2)2 - 0.000245(v+1/2)3 except for v=1, 2, and 3 all of which are close to the intersection of the two potential curves. |
| 3 | A0 = +342.66 Veseth, 1971, A1 = +342.06 Veseth, 1971 [as recalculated in Veseth, 1971 from the data of Stenvinkel, 1936]. |
| 4 | Rotational constants for v=0 and 1 as recalculated in Veseth, 1971 from the data of Stenvinkel, 1936. Λ-type doubling Δνfe(2Π1/2, v=0) ~ 0.269(J+1/2) - ..., and in 2Π3/2 [see Fujioka and Tanaka, 1937 and Stenvinkel, 1936]. |
| 5 | D1 = 4.46E-4; H0 = +1.34E-8, H1 = +0.9E-8. |
| 6 | J'=1/2 (average of F1 and {F2}) relative to N"=0. A different definition was used in Stenvinkel, 1936. |
| 7 | ωeze = -0.4339. Very rapid convergence. The constants (from Stenvinkel, 1936) lead to a discrepancy of nearly 6 cm-1 for the highest observed level, v=5. |
| 8 | Spin doubling, Δ v12(v=0) = +0.254(N+1/2) - ... [ Stenvinkel, 1936, see also Veseth, 1970], decreasing rapidly with increasing v. |
| 9 | αv= -0.03765(v+1/2)2 + 0.00897(v+1/2)3 - 0.001479(v+1/2)4. |
| 10 | D1(E-4 cm-1)= 5.00, D2(E-4 cm-1)= 5.49, D3(E-4 cm-1)= 6.58, D4(E-4 cm-1)= 8.40, D5(E-4 cm-1)= 10.5. Also higher order terms, see Stenvinkel, 1936. |
| 11 | ESR sp. 13 |
| 12 | Short extrapolation for the ground state. |
| 13 | In Ar matrix at 4 K Knight and Weltner, 1971. |

| 15 | A0 = +342.82 Veseth, 1971, as recalculated in Veseth, 1971 from the data of Fujioka and Tanaka, 1937. |
| 16 | Rotational constants recalculated in Veseth, 1971 from data in Fujioka and Tanaka, 1937. Λ-type doubling Δνfe(2Π1/2) ~ +0.170~(J+1/2) - ,.., see Fujioka and Tanaka, 1937. |
| 17 | H0 = +1.6E-8. |
| 18 | Spin doubling Δν12 = +0.131(N+1/2), see Fujioka and Tanaka, 1937. |
