Notes
| 1 | Large spin doubling, γ0= (-)0.4940. v=0 perturbed for N>30. |
| 2 | Recalcu1ated using bandheads of the B-X 0-0 and 1-0 sequences only. |
| 3 | Bv appears to depend irregularly on v; see Effantin, Bacis, et al., 1971. |
| 4 | From Effantin, Bacis, et al., 1971. The vibrational numbering in Gatterer and Krishnamurty, 1952, differs by -1 in both upper and lower state leading to v00 ~19332 Gatterer and Krishnamurty, 1952. |
| 5 | Large hyperfine splitting, 4b = 0.663 cm-1 Bacis and Bernard, 1973. |
| 6 | Thermochemical value (mass-spectrometry) Ames, Walsh, et al., 1967. recalculated Smoes, Coppens, et al., 1969. |
