The fundamental features of the hyrer-Raman scattering phenomenon due to Raman-inactive mode of lattice vibration have been experimentally studied for SrTiO 3 , with special emphasis on polarization properties and an application of the hyper-Raman scattering to observation of the soft mode. The results of polarization properties are compared with the selection rules based on group theory. Variation of the “ferroelectric” soft-mode has been measured as a function of temperature from 300 K to 4.6 K. Further, a comparison between the forward- and right-angle scatterings is given from the experimental point of view.
