Notes

1DeltaG(3/2) = 80.8.
2Lambda-type doubling, Deltanuef(v=0) = +0.0047J(J+1). Breaking off due to predissociation above J'= 9,7,4 in v'= 0,1,2, respectively; the limiting curve intersects the ordinate axis near 22250 cm-1 above X 1Sigma(v=0,J=0). A few additional diffuse lines have been observed as well as fragments of an "extra" band; see 3.
3B1 = 1.915, B2 = 1.363. Dv values are also given Neuhaus, 1958, but these constants are not sufficient to reproduce the levels of this perturbed state. Zeeman effect studies Larsson and Neuhaus, 1964.
4Effective constants determined by Ginter, 1963,110. For a more rigorous treatment of the fine structure of a 3Pi see Veseth and Lofthus, 1974.
5Predissociation in v=0 above J=26 (3Pi-) and 27 (3Pi+), in v=1 above J=17 (3Pi+), The break-off points are in agreement with the limiting curve of dissociation for 3Pi1+ Ginter, 1963.
6missing note
7Average constants for 3Pi1+ and 3Pi1-; The Lambda-type doubling is irregular, see Veseth and Lofthus, 1974, and may be caused by the unobserved a' 3Sigma+ state. Zeeman effect studies Larsson and Neuhaus, 1964.
8The 3Pi1 and 3Pi0+ components have nearly identical limiting curves of predissociation; the derived dissociation limit at 20125 cm-1 above X 1Sigma, v=0, J=0, appears to correspond to a potential maximum at ~3.3 Å Ginter, 1963. Possible correlations of the low-lying states of InH with those of the separated atoms have been discussed by Ginter and Battino, 1965 and more recently, by Veseth and Lofthus, 1974.
9The hyperfine structure of J=1 has been investigated both experimentally Neuhaus, 1958, Neuhaus, 1958, 2, Larsson, Neuhaus, et al., 1968 and theoretically Freed, 1966, Veseth, 1976.

22B1 = 1.098, B2 = 0.981, B3 = 0.751. Dv values have been determined Neuhaus, 1958, 2 but their meaning is limited in view of the strong perturbations affecting this state. Fragments of three "extra" bands with v"=0,1,2.
23DeltaG(3/2) = 857.42.
