Abstract

The transverse complex dielectric constant of KH₂PO₄ is calculated using the transverse pseudo-spin model for temperatures above and below T_c. We predict the existence of a central protonic E-mode below T_c thereby explaining recently observed anomalies in the low-frequency transverse Raman spectra and the dynamical dielectric constant of KH₂PO₄.
