Notes
1 | This level interacts with v=1 of C 1Π Larsson and Neuhaus, 1963. |
2 | ΔG(3/2) = 56.2. |
3 | B0+ - B0- = +0.006. |
4 | B1 = 1.84, B2 = 0.7. |
5 | D1 = 60E-4. |
6 | ΔG(3/2)= 474.9, ΔG(5/2)= 393.0, ΔG(7/2)= 402.2, ΔG(9/2)= 416.0, ΔG(11/2)= 426.1. |
7 | Anomalous potential curve, see Ginter and Battino, 1965, Larsson and Neuhaus, 1966. |
8 | B1= 3.916, B2= 3.201, B3= 2.981, B4= 2.856, B5= 2.780, B6= 2.692. |
9 | Lines become increasingly diffuse with increasing rotation. |
10 | For higher Dv values see Grundstrom and Valberg, 1938, Neuhaus and Muld, 1959. |
11 | RKR potential curve Ginter and Battino, 1965. |
12 | From the highest observed level in C 1Π Larsson and Neuhaus, 1963; this state dissociates to 2P3/2 + 2S. Flame photometry Bulewicz and Sugden, 1958 gives 1.91 eV. |
13 | From the value for TlH. |
14 | v'=0 not observed, possibly because of predissociation by the repulsive 3Π1 state; see Larsson and Neuhaus, 1966. |
15 | ΔG(3/2) = 439.13, ΔG(5/2)= 314.61, ΔG(7/2)= 279.65, ΔG(9/2)= 281.23, ΔG(11/2)= 288.14. |
