text: LiTaO3 and LiNbO3 crystals are investigated here in a combined experimental
and theoretical study that uses Raman spectroscopy in a complete set of scattering
geometries and corresponding density-functional theory calculations to provide
microscopic information on their vibrational properties. The Raman scattering
efficiency is computed from first principles in order to univocally assign the
measured Raman peaks to the calculated eigenvectors. Measured and calculated Raman
spectra are shown to be in qualitative agreement and confirm the mode assignment
by Margueron et al. [J. Appl. Phys. 111, 104105 (2012)], thus finally settling
a long debate. While the two crystals show rather similar vibrational properties
overall, the E-TO9 mode is markedly different in the two oxides. The deviations
are explained by a different anion-cation bond type in LiTaO3 and LiNbO3 crystals.
