摘要：

We report both polarized Raman and unpolarized infrared-reflectivity spectra of Bi2CuO4. $5A sub 1g, 4B2g, 6Eg, and 14 ir modes are clearly observed. The assignment of the observed Raman modes is given according to Cartesian symmetry coordinates and preliminary force-constant calculation on the basis of a rigid-ion model and by comparison with the spectra of the isostructural compound Bi2PdO4. Similarities between vibrational properties of Bi2CuO4 and high-Tc superconducting oxides are discussed. © 1990 The American Physical Society.
