Analysis of the dielectric relaxation phenomena in Bi2O3-ZnO-Nb2O5 cubic pyrochlore utilizing the Arrhenius equation is revisted to include recent high-frequency measurements. The attempt jump frequency obtained from the Arrhenius fit (űo÷4.385 THz) is found in correspondence with the resonant frequences of the polar phonon modes previsously identified by infrared spectroscopy.
