Paper Abstract
The Raman spectra of Gly(DOT)H3PO3 were investigated over the internal frequency range 400 - 3200 cm-1. The measurements have been performed in the temperature range 175 - 250 K covering paraelectric-ferroelectric P21/a-P21 phase transition. The Raman study revealed the dynamical disorder of protons which is coupled to the motions of glycinium cations. Two types of glycinium cations were observed in the ferroelectric phase instead of one in paraelectric phase. The obtained results confirm the order- disorder nature of a proper ferroelectric phase transition of second order.
