The isotopic shift of the 6{ital p}{sup 2} {ital P}{sub 0}{r arrow}6{ital p}{sup 2} {sup 3}{ital P}{sub 1} (1.28 {mu}m) magnetic-dipole transition in Pb, which had been previously estimated incorrectly in the literature, has been measured, together with the magnetic hyperfine constant of the {sup 3}{ital P}{sub 1} level in {sup 207}Pb. The shifts of the {sup 206}Pb and {sup 207}Pb lines from the {sup 208}Pb position are {delta}(206--208)=220.4(15) MHz and {delta}(207--208)=138.0(17) MHz, and the hyperfine constant {ital A}(6{ital p}{sup 2} {ital P}{sub 1})={minus}2388.2(45) MHz. Inclusion of the shifts in calculated optical rotation line shapes removes long-standing discrepancies between theory and experiment, which have limited the precision of parity-nonconservation measurements in Pb.
