Notes

1From the A2 larrow X2 progression; slightly different numbers are obtained from A2 larrow X1. The assignements of both progressions are tentative.
2Only B3 = 0.540 and B5 = 0.532 have been measured. Individual rotational lines are diffuse for v'geq 3. Bands with v' geq 7 are very diffuse.
3Based on the assignments of progressions A2 larrow X2 and A2 larrow X1; from the ESR spectrum Carrington, Currie, et al., 1969 derive A0 = -387 ± 25 Carrington, Currie, et al., 1969.
4Microwave sp. 6
5From the predissociation in the A1 larrow X1 bands; see 2.
6muel(v=0) = 0.794 D Amano and Hirota, 1973; Byfleet, Carrington, et al., 1971 obtain muel(v=0)= 0.87 D Byfleet, Carrington, et al., 1971. Hfs parameter a + 1/2(b+c) = 428.60 MHz Carrington, Currie, et al., 1969, Amano and Hirota, 1973.
