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