Abstract
The Raman spectrum of LiNbO3 has been measured for various scattering configurations in crystals with different compositions. The comparison between spectra recorded for the congruent and the nearly stoichiomet ric crystals shows significant differences in the shape and the number of Raman peaks. The analysis of results leads to a new and complete a ssignment of the long-wavelength optical phonons in LiNbO3.
