Abstract
In the last few years the assignment of the optical phonons of LiNbO3 to the different symmetry species was often changed. We therefore concluded that the relative intensities of the Raman lines must be re-examined. According to all elements of the Raman tensor, the fundamental spectra were recorded separately as far as possible. The relative intensities are listed within an error of 7 or 40 percent, each according to signal-to-noise-ratio and/or overlapping of nearby lines.Keywords
