Notes

1DeltaG(3/2) = 254.
2Weak diffuse bands.
3DeltaG(3/2) = 149.
4Three sharp bands.
5DeltaG(3/2)= 216,DeltaG(5/2)= 217.
6Weak system.
7DeltaG(3/2,5/2) = 195,205 Topouzkhanian, Sibai, et al., 1974; G(7/2) = 196 47. Bands of 121Sb2 Sibai, Topouzkhanian, et al., 1975.
8DeltaG(3/2)= 216 Donovan and Strachan, 1971,DeltaG(5/2)= 217 Donovan and Strachan, 1971, DeltaG(7/2)= 220 Donovan and Strachan, 1971,DeltaG(9/2)= 246 Donovan and Strachan, 1971 [flash photolysis of SbH3]; Topouzkhanian, Sibai, et al., 1974 [high tempereature absorption] give no assignments.
9Three bands appear diffuse.
10 Topouzkhanian, Sibai, et al., 1974 express doubts about the correctness of the analysis.
11DeltaG(3/2) = 541, DeltaG(5/2)= 528, DeltaG(7/2)= 477, DeltaG(9/2)= 517, DeltaG(11/2)= 548, DeltaG(13/2)= 472. The constants assume v'=0,v"=2 for the first band at 43897 cm-1.
12Single progression, observed in 121Sb2.
13Levels up to v'=17 have been observed; the DeltaG values are irregular due to perturbations and vary between 208 and 228. Nakamura and Shidel, 1935 give different assignments and constants.
14Constants for 121,123Sb2 from the rotational analysis of the B rarrow X 2-2 band by Sfeila, Perdigon, et al., 1972 who give also constants for 121Sb2 and 123Sb2.
15Thermochemical value (mass-spectrometry) DeMaria, Drowart, et al., 1959, Kordis and Gingerich, 1973.
