Abstract

Polarized Raman spectra of single-crystal LiCuVO4 containing quasi-one-dimensional cuprate chains are measured. The force constants of the valence force field are calculated for the phonon modes at the center of the Brillouin zone with an accuracy sufficient to describe the experiment. From the results, it follows that the crystal contains rigid Cu-O-V-Cu-O-V structural rings with a charge distributed along their bonds.
