We report detailed spectroscopic measurements of the X(0)[1+](v=0)-> B(1)[3Π](v=5) transition in PbO. Using a Stark-modulated laser absorption technique, we have measured the hyperfine constant of (PbO)-Pb-207 in the B(1) state, as well as the B(1)(v=5) rotational constant, X-B isotope shifts, etc. The hyperfine constant of the B(1) state is of interest as a benchmark for calculations of PbO electronic structure related to experiments to search for the electric dipole moment of the electron.
