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