Notes
1 | A0 = -160.2 +... |
2 | For Λ-type doubling see Aslund, Neuhaus, et al., 1965. |
3 | Lines with J' ≥ ~11 1/2 are diffuse. |
4 | These band origins are corrected for J-independent terms not usually taken into account in these tables. |
5 | Lines with J' ≥ ~12 are diffuse, both in absorption and in thermal emission. |
6 | From v=0, ..., 3 only. See 7. |
7 | All observed levels perturbed. Heimer Heimer, 1937, Heimer, 1937, 2 obtained the following Bv values by extrapolation to J=0: v=0, Bv = 5.113 Heimer, 1937, Heimer, 1937, 2 (increasing with J), v=1, Bv = 5.350 Heimer, 1937, Heimer, 1937, 2 (increasing with J), v=2, Bv = 5.480 Heimer, 1937, Heimer, 1937, 2 (increasing with J), v=3, Bv = 5.900 Heimer, 1937, Heimer, 1937, 2 (decreasing with increasing J). A reanalysis of the red band systems of NiH is considered necessary by Aslund, Neuhaus, et al., 1965. |
8 | Λ-type doubling increases rapidly above J=9 1/2. See Heimer, 1937. |
9 | A0 = -490.2 +... |
10 | From isotope relations. |
11 | D1= 7.8E-4. Heimer Heimer, 1937, Heimer, 1937, 2 finds αe= 0.248, D1= 5.1E-4, but his interpretation of a perturbation in the 0-1 band of C1-X1 is questioned by Aslund, Neuhaus, et al., 1965. |
12 | From the predissociation in C1. |
13 | It is not certain that the level assigned as v=1 (B1 = 3.410, D1 = 3.6E-4) belongs to the same electronic state. |
14 | Lines of the 1-0 band with J ≥ 9 1/2 are broad. |
15 | D1 = 2.0E-4. |
16 | All observed levels perturbed. Extrapolation to J=0 gives B0 = 2.930, B1 = 2.710, B2 = 2.463. |
17 | D1 = 1.40E-4. |
