Notes
1 | Very strong. |
2 | From the interpretation of the VUV absorption spectrum Donovan, Little, et al., 1972; from the paramagnetic resonance spectrum Radford, 1964 obtains A0= -2250 Radford, 1964. |
3 | EPR sp. |
4 | From a tentative interpretation of several Rydberg series (e.g. C,P,Q,...) by Donovan, Little, et al., 1972. |
