Condensed Phase Spectrum
Notice: This spectrum may be better viewed with a Javascript and HTML 5 enabled browser.
Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. More information on the manner in which spectra in this collection were collected can be found here.
Notice: Concentration information is not available for this spectrum and, therefore, molar absorptivity values cannot be derived.

Notes
| 1 | Strong perturbations make the constants for this state somewhat uncertain. For 206Pb0. Be = 0.2421 Barrow, 1970, αe = 0.0026 Barrow, 1970. |
| 2 | Perturbations in v=0 Ram, Singh, et al., 1973. |
| 3 | RKR potential functions Nair, Singh, et al., 1965. |
| 4 | Franck-Condon factors Nicholls, Fraser, et al., 1959. |
| 5 | Barrow, 1970 quotes Be = 0.2491 Barrow, 1970 (extrapololated from v=6,7) for 206PbO. |
| 6 | The vibrational numbering of Howell, 1936 has been increased by 2. |
| 7 | Vibrational 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. |
| 8 | Rotational perturbations in v=1 Ram, Singh, et al., 1973. |
| 9 | Lifetimes 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. |
| 10 | Relative intensities Dube, Upadhya, et al., 1970; transition probabilities Dube, 1971. |
| 11 | Constants 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from band heads with v' ≤ 6 Linton and Broida, 1976, in good agreement with results quoted by Barrow, 1970 from an unpublished thesis by Travis (rotational analysis of v=0... 3 of 206PbO) but considerably smaller than earlier values (ωe = 451.7, ωexe = 3.33) proposed by Bloomenthal,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. |
| 12 | Ground state levels observed to v=l5 Linton and Broida, 1976. |
| 13 | Microwave sp. 15 |
| 14 | Thermochemical 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. |
