| Abstract: | The temperature behavior of polarized Raman spectra of a-domain PbTiO3 single crystals has been investigated. The spectra obtained are fit by a damping harmonic oscillator model with allowance for a complex background structure. A full set of oscillator parameters of all phonon modes in the frequency range 12 < ν < 1200 cm?1 is obtained and their temperature dependences in the range from 300 to 800 K are presented. |
