✦ Synopsis
The reliability of the MKN (Morse-Korwar-Navati) oscillator model in representing the potential curves of the XI.~ and the B1 state of PbO has been established by comparison with the Morse and Hulburt-Hirschfelder (H-H) models. Wave functions computed by the authors' approximation method are used to calculate Franck-Condon factors and r-centroids appropriate to the MKN and the H-H potential. Relevant results are reported for the bands of the B1-X12 system of the PbO molecule.
