We consider 51 odd-parity configurations of Pb I utilizing all data available from absorption and emission spectroscopy measurements, photoionization experiments, and ejected-electron spectroscopy. These include detailed results of our earlier laser spectroscopic studies of the 6[ital s][sup 2]6[ital pns], 6[ital s][sup 2]6[ital pnd], and 6[ital s][sup 2]6[ital png] Rydberg levels [P. Buch, J. Nellessen, and W. Ertmer, Phys. Scr. 38, 664 (1988)]. The analysis has been performed with the aid of a linked-parameter method of level-fitting calculations in a large multiconfiguration basis. New identifications of the 6[ital s]6[ital p][sup 3] levels are proposed and reasons for their assignment are presented. On the basis of our level-fitting calculations precise assignments of 242 odd-parity electronic energy levels are given. Eigenvectors obtained in these calculations can be used to calculate the values of other physical observables with high precision. In addition, we have also made appropriate pseudorelativistic Hartree-Fock [ital ab] [ital initio] calculations of level structure, oscillator strengths, and autoionization widths for procedural guidance and comparison purposes.
