<jats:p> The dielectric ceramic materials, 0.143BaO-0.714TiO<jats:sub>2</jats:sub>-0.143 rare earth oxides (REO<jats:sub> <jats:italic>x</jats:italic> </jats:sub>), have unique dielectric properties at microwave frequencies, which depend on the rare earth element (RE=Pr, Nd, Sm). In order to study the effect of the rare earth ions on dielectric properties, infrared reflection spectra of these ceramics were measured from 50 to 4000 cm<jats:sup>-1</jats:sup> at room temperature. These data were analyzed according to the model proposed by Gervais and Piriou. Also, the fourth-order dielectric constants of these materials were estimated for the purpose of investigating the relationship between the dielectric loss and the anharmonic terms in the potential energy. </jats:p>
