Polarized spectra of the Raman scattering of tetragonal and orthorhombic single crystals of õ÷Á2óÉ3ïÌ have been recorded. The dependence of the frequency of the valence vibration of the Cu (1) -O (1) -Cu (2) bond on the lattice constant Ó has been established. The nature of the interatomic interaction is shown to depend on the lattice symmetry.
