Notes
| 1 | ΔG(3/2) = 80.8. |
| 2 | Λ-type doubling, Δνef(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 1Σ(v=0,J=0). A few additional diffuse lines have been observed as well as fragments of an "extra" band; see 3. |
| 3 | B1 = 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. |
| 4 | Effective constants determined by Ginter, 1963,110. For a more rigorous treatment of the fine structure of a 3Π see Veseth and Lofthus, 1974. |
| 5 | Predissociation in v=0 above J=26 (3Π-) and 27 (3Π+), in v=1 above J=17 (3Π+), The break-off points are in agreement with the limiting curve of dissociation for 3Π1+ Ginter, 1963. |
| 6 | missing note |
| 7 | Average constants for 3Π1+ and 3Π1-; The Λ-type doubling is irregular, see Veseth and Lofthus, 1974, and may be caused by the unobserved a' 3Σ+ state. Zeeman effect studies Larsson and Neuhaus, 1964. |
| 8 | The 3Π1 and 3Π0+ components have nearly identical limiting curves of predissociation; the derived dissociation limit at 20125 cm-1 above X 1Σ, 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. |
| 9 | The 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. |
| 10 | RKR potential curves Ginter and Battino, 1965. |
| 11 | ωeye= -6.83 |
| 12 | γe= -0.0390 |
| 13 | H0= -3.76E-8. |Dv| and |Hv| increase rapidly with v. |
| 14 | H0= -2.9E-8. |
| 15 | ωeye= 0.308 |
| 16 | γe= +0.00213 |
| 17 | H0= +0.463E-8. |
| 18 | From the predissociations in A 1Π and a 3Π. |
| 19 | From the value for InH and the predissociation in A 1Π. |
| 20 | ΔG(3/2) = 62.8, ΔG(5/2) = 51.1. |
| 21 | Λ-type doubling, Δνef(v=0)= +0.0012J(J+1). Breaking-off due to predissociation above J'=13(v'=0,1), 10(v'=2), 7(v'=3). |
| 22 | B1 = 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. |
| 23 | ΔG(3/2) = 857.42. |
