1This level interacts with v=1 of C 1Pi Larsson and Neuhaus, 1963.
2DeltaG(3/2) = 56.2.
3B0+ - B0- = +0.006.
4B1 = 1.84, B2 = 0.7.
5D1 = 60E-4.
6DeltaG(3/2)= 474.9, DeltaG(5/2)= 393.0, DeltaG(7/2)= 402.2, DeltaG(9/2)= 416.0, DeltaG(11/2)= 426.1.
7Anomalous potential curve, see Ginter and Battino, 1965, Larsson and Neuhaus, 1966.

9Lines become increasingly diffuse with increasing rotation.
10For higher Dv values see Grundstrom and Valberg, 1938, Neuhaus and Muld, 1959.
11RKR potential curve Ginter and Battino, 1965.
12From the highest observed level in C 1Pi Larsson and Neuhaus, 1963; this state dissociates to 2P3/2 + 2S. Flame photometry Bulewicz and Sugden, 1958 gives 1.91 eV.
13From the value for TlH.
14v'=0 not observed, possibly because of predissociation by the repulsive 3Pi1 state; see Larsson and Neuhaus, 1966.
