Paper Abstract

Dispersion of low frequency polaritons have been studied in PbTiO3 crystal in the 200 - 3000 cm-1 wave vector range. Their behavior allows a new insight into the description of the internal processes involved: A1-symmetry pure damped oscillatory response and E-symmetry more complicated mechanism.
