Notes

1RKR potential curves Nair, Singh, et al., 1965, 93.
2Bands in the near UV and visible region (3490-6170 ) first described by Barrow and Jevons, 1939 have been shown Bredohl, Cornet, et al., 1975 to be part of the ErarrowX system (1leqv'leq17, 20leqv"leq51). Franck-Condon factors Katti and Korwar, 1975.
3The constants for these states have been derived Nilheden, 1956 from perturbations in D 1Pi; the vibrational numbering is uncertain except for C 1Delta.
4Numerous perturbations due to interactions with e 3Sigma-, C 1Delta, and I 1Sigma-.
5Only v'=0 observed
6From studies of four different isotopes the equilibrium internuclear distance at the minimum of the Born-Oppenheimer potential curve can be derived: re(B0) = 1.929264 Tiemann, Renwanz, et al., 1972.
7Microwave sp. 9
8From a short extrapolation of the vibrational levels of the E state Robinson and Barrow, 1954 assuming dissociation into 3P2 + 3P2 Barrow, 1970.
9muel(v=0) = +1.73 D (+SiS-), see Murty and Curl, 1969, Hoeft, Lovas, et al., 1969, Tiemann, Renwanz, et al., 1972; gJ = -0.09097- 0.000296(v+1/2) Honerjager and Tischer, 1973; Si33S hyperfine structure Hoeft, Lovas, et al., 1969; adiabatic and non-adiabatic corrections Tiemann, Renwanz, et al., 1972.
