Notes

1Further unclassified absorption bands between 68100 and 69800 cm-1.
2Average B and D, B(1+) - B(1-) = +0.064.
3Average B and D, B(1+) - B(1-) = -0.014.
4The constants refer to the 0+ component; the numbering of the Q branch (0- component, v00 ~ 69147.0) is uncertain.
5Vibrational numbering uncertain; the numbers given refer to the lowest level observed in absorption for which v is probably fairly high. Several higher vibrational levels have been found; strong perturbations.
6B1 = 2.974 (perturbed at intermediate J), B2 = 2.802.
7Constants refer to the Ω+ component.
8Very diffuse feature.
9The 1-0 band is quite diffuse and its assignment uncertain.
10Diffuse Q heads only.
11Diffuse, unresolved Q branch.
12missing note
13Continuous absorption starting at 33000 with maximum at 45000 cm-1.
14At 37550 cm-1 26% of the absorption is due to 3Π0+; see 22 of HI.
15From the IR spectrum Hurlock, Alexander, et al., 1971.

18Rotation sp. 21
19From D00(HI).
20Broad P and R lines, diffuse and unresolved Q branch.
