Abstract
The polarized Raman scattering measurements from tetragonal BaTiO3 were made, with incident and scattered light polarized both in (x, z) scattering plane, having a crystal rotated about y-axis perpendicular to the plane. The Raman spectra were obtained at kiks = 120° scattering geometry. Our experimental results of angular dependence of oblique phonon frequencies were analysed by the Merten's theory.
