Notes

1Strong perturbations make the constants for this state somewhat uncertain. For 206Pb0. Be = 0.2421 Barrow, 1970, αe = 0.0026 Barrow, 1970.
2Perturbations in v=0 Ram, Singh, et al., 1973.
3RKR potential functions Nair, Singh, et al., 1965.
4Franck-Condon factors Nicholls, Fraser, et al., 1959.
5 Barrow, 1970 quotes Be = 0.2491 Barrow, 1970 (extrapololated from v=6,7) for 206PbO.
6The vibrational numbering of Howell, 1936 has been increased by 2.
7Vibrational constants from Howell, 1936; Barrow, Deutsch, et al., 1961 give ωe = 493.5 Barrow, Deutsch, et al., 1961, ωexe= 2.26 Barrow, Deutsch, et al., 1961. Irregular vibrational intervals.
8Rotational perturbations in v=1 Ram, Singh, et al., 1973.
9Lifetimes τ[B(v=0,1)] = 2.58 μs Oldenborg, Dickson, et al., 1975; τ[A(v=2)] = 3.75 μs Oldenborg, Dickson, et al., 1975.
10Relative intensities Dube, Upadhya, et al., 1970; transition probabilities Dube, 1971.
11Constants derived from band heads with v' ≤ 6 Linton and Broida, 1976, in good agreement with results quoted by Barrow, 1970 from an unpublished thesis by Travis (rotational analysis of v=0... 3 of 206PbO) but considerably smaller than earlier values (ωe = 451.7, ωexe = 3.33) proposed by Bloomenthal, 1930.
12Ground state levels observed to v=l5 Linton and Broida, 1976.
13Microwave sp. 15
14Thermochemical value (mass-spectrometry) Drowart, Colin, et al., 1965. From the Pb + O3 chemiluminescence spectrum under single-collision conditions Oldenborg, Dickson, et al., 1975 derive D00 ≥ 3.74 eV.
15Stark effect, μel(v=0) = 4.64 D Hoeft, Lovas, et al., 1969. Zeeman effect, gJ(v=0) = -0.1623 Honerjager and Tischer, 1973.
