Notes
| 1 | Additional peaks in the electron energy loss spectrum at 7.8, 15.5, 19.0, 23.0 eV Geiger and Pfeiffer, 1968. Davidovits and Brodhead, 1967 give absorption cross sections from 34000 to 50000 cm-1. |
| 2 | There is no conclusive evidence yet for the identity of the upper states observed in the absorption and emission spectra. |
| 3 | Diffuse absorption bands (fluctuation b.) 30000 - 38300 cm-1; long lower state vibrational progression in chemiluminescence from 18000 to 26000 cm-1. |
| 4 | From the IR spectrum Rice and Klemperer, 1957. From the rotational constants Clouser and Gordy, 1964 calculate ωe = 233.34, ωexe = 0.856. |
| 5 | Rot. vibr. b. |
| 6 | eqQ(85Rb) = -52.675 + 0.38v MHz v=0,1,2 Trischka and Braunstein, 1954 eqQ(35Cl) = +0.774 - 0.155v MHz v=0,1,2 Trischka and Braunstein, 1954; for constants of 87Rb35Cl see Bolef and Zeiger, 1952, Trischka and Braunstein, 1954. |
| 7 | μel[D] = 10.483 + 0.054(v+1/2), v = 0,1,2. |
| 8 | gJ = (-)0.0183 μN. |
| 9 | Thermochemical value Brewer and Brackett, 1961; flame photometric value 4.40 eV Bulewicz, Phillips, et al., 1961. |
| 10 | Onset of a broad unresolved photoelectron peak with maximum at 8.74 eV Goodman, Allen, et al., 1974, Potts, Williams, et al., 1974. |
| 11 | From D00(RbCl) and the ionization potentials of Rb and RbCl. |
| 12 | From maxima of the photoelectron spectrum Potts, Williams, et al., 1974, missing citation; the halogen 3p spectrum is unresolved. The complexity of the metal 4p photoelectron spectrum is tentatively attributed to configuration interaction in RbBr. See ref 12 of RbBr. |
