Notes
| 1 | Spin coupling constants for v=0: A(v=0) = 20.41 Klynning, Lindgren, et al., 1965, AJ(v=0) = 0.0625 Klynning, Lindgren, et al., 1965, γ(v=0) = 1.23 Klynning, Lindgren, et al., 1965. For a more elaborate evaluation of these constants (including centrifugal distortion) see Kovacs and Vujisic, 1971. |
| 2 | Rotational constants of Klynning, Lindgren, et al., 1965 based on a modified Hill-Van Vleck expression; see also Kovacs and Vujisic, 1971. A case "c" treatment of the same data is given by Veseth, 1973. |
| 3 | Broadening of absorption lines above N' ~ 14 Klynning, Lindgren, et al., 1965, sharp cut-off in emission at N'=17 Watson and Simon, 1939. |
| 4 | H0 = -2.3E-7; see 2. |
| 5 | Spin splitting constants for v=0: λ(v=0) = 45.78 Klynning, Lindgren, et al., 1965, γ1(v=0) = 0.190 Klynning, Lindgren, et al., 1965, γ2(v=0) = 0.191 Klynning, Lindgren, et al., 1965. ΔB is the difference in B values between the states Ω = 1/2 and 3/2: ΔB = -0.0266 Klynning, Lindgren, et al., 1965. All constants derived by Klynning, Lindgren, et al., 1965 according to the modified expressions [see Klynning, Lindgren, et al., 1965 for the energy levels of a 4Σ state Hougen, 1962. For further refinements see Kovacs and Korwar, 1971, Kovacs and Pacher, 1971. The case "c" treatment of the same data by Veseth, 1973 gives B0 = 5.404, (Ω=1/2) Veseth, 1973 and B0 = 5.339, (Ω= 3/2) Veseth, 1973, respectively. For a discussion of 4Σ1/2- in terms of case "a'" coupling conditions see Kopp and Hougen, 1967. |
| 6 | H0 = -3.3E-8. |
| 7 | Rotational intensity distribution Klynning, 1966, Kopp and Hougen, 1967. |
| 8 | A0 = +2178.88 + 0.01719J(J+1) Klynning, Lindgren, et al., 1965; see, however, Kovacs and Vujisic, 1971. |
| 9 | Λ-type doubling Δ vfe(2Π1/2, v=0) = +1.003(J+1/2) - 1.76E-4(J+1/2)3 Klynning, Lindgren, et al., 1965. |
| 10 | From the predissociation in A 2Δ assuming dissociation into 3P2 + 2S. |
| 11 | Spin coupling constants for v=0: A(v=0)=8.52, AJ(v=0)= 0.0225, γ(v=0) = 0.555. The large difference from SnH remains unexplained; see Veseth, 1971, Veseth, 1973. |
| 12 | H0 = -0.135E-7; see 2. |
| 13 | Spin splitting constants for v=0: λ(v=0) = 45.0, γ1(v=0) = 0.076, γ2(v=0) = 0.0883. ΔB= -0.012 see 5. |
| 14 | H0 = -0.13E-8. |
| 15 | A0 = 2177.05 + 0.0080J(J+1). |
| 16 | Δ vfe(2Π1/2,v=0) = +0.5076(J+1/2) - 0.000045(J+1/2)3. |
