title: The VUV Absorption Spectrum of Lead Monoxide.
abstract: The VUV absorption spectrum of PbO vapor down to 300 Å has been observed for the first time. Four ionization energies have been determined from Rydberg series at 8.73, 8.83, 12.81, and 26.28 eV corresponding to the X(2)Pi, A(2)Sigma(+), B(2)X(+), and C(2)Sigma(+) electronic states of the PbO(+) ion.
