Notes
| 1 | Observed value. Te, ωe, ωexe represent only v'=1,2,...; the v'=0 bands are displaced by ~12 cm-1 to lower energies owing to a perturbation. |
| 2 | Unclassified bands in the region 3100 - 2750 Å (32200 - 36400 cm-1). |
| 3 | RKR potential functions Nair, Singh, et al., 1965. |
| 4 | Also observed as laser-excited emission in Ne, Ar, Kr, SF6 matrices Teichman and Nixon, 1975. Lifetimes in solid Ar have been measured for a,A,B Teichman and Nixon, 1975: τ(a)=260 μs, τ(A)=0.95 μs, τ(B)=1.8 μs. |
| 5 | Rotational constants for 208Pb32S; Be values for other isotopes and adiabatic corrections Tiemann, Stieda, et al., 1975. |
| 6 | αv= -5.31E-7(v+1/2)2 - 5.0E-9(v+1/2)3. |
| 7 | Vibration sp. 10 |
| 8 | Dipole moment of 208Pb32S, μel(v=0) = 3.59 D Hoeft, Lovas, et al., 1969, from Stark effect of rotation spectrum Hoeft, Lovas, et al., 1969. A somewhat different value, μel(v=0)= 4.02 D Murty and Curl, 1969, is given by Murty and Curl, 1969. gJ = -0.06422 Tiemann, Stieda, et al., 1975 [Honerjager and Tischer, quoted in Tiemann, Stieda, et al., 1975]. |
| 9 | Thermochemical value (mass-spectrometry Colin and Drowart, 1962), revised Uy and Drowart, 1969. There appears to be a convergence of the E → X bands near 2715 Å Vago and Barrow, 1947. If it is assumed that this limit corresponds to 3P1 + 3P1 one finds D00 = 3.54 eV Barrow, Fry, et al., 1963. |
| 10 | In Ar matrix at 12 K. Teichman and Nixon, 1975 have also observed the Raman spectrum of the PbS fundamental in solid argon. |
