Abstract : The report deals with the infrared transmitting properties of fluorite structure oxides and the heavy metal covalent oxides of bismuth and lead. Transmission data for single crystal ThO2 are given. A theoretical analysis of the vibrational modes, selection rules and IR spectra of the powders are given for alpha-Bi2O3, PbO.6Bi2O3, tetragonal PbO, orthorhombic PbO, and Sr2PbO4. (Author)
