Notes
| 1 | Te = 45918.0 Sharma, 1946. |
| 2 | Slightly different constants in Sharma, 1946. |
| 3 | A different band system in the same region (Te= 16362.3, ω'e= 141.4, ω'ex'e = 0.224) was reported earlier by Walker, Straley, et al., 1938 in absorption but not found by Grove and Ginsburg, 1960. |
| 4 | Rotational constants for 208Pb130Te. |
| 5 | αv= -0.56E-7(v+1/2)2 - 0.37E-9(v+1/2)3. |
| 6 | Microwave sp. 8 |
| 7 | Thermochemical values of Pashinkin and Novoselova, 1959 and Porter, 1961, corrected by Uy and Drowart, 1969 for change in value of D00(Te2). |
| 8 | Dipole moment μel(v=0) = 2.73 D Hoeft, Lovas, et al., 1970 from Stark effect measurements on pure rotational transitions of 208Pb130Te Hoeft, Lovas, et al., 1970. Zeeman effect Honerjager and Tischer, 1974, gJ(v=0) = - 0.0l800 μN Honerjager and Tischer, 1974 for 208Pb130Te. |
