Polarized reflectivity spectra of PbMoO4 crystals have been measured using synchrotron radiation up to 20 eV. The optical constants for the crystallographic axes are derived by using a Kramers–Kronig analysis. It is found that the exciton band at 3.6 eV shows a doublet structure with distinct dichro...
