The dielectric properties in a liquid crystal exhibiting ferro, ferri, and antiferroelectric mesophases have been studied. The dielectric response, although complex, allows the characterization of teh various phase transitions in the material. The modes corresponding to the antiferroelectric mesophases are found to be particularly complex and cannot be interpreted on the basis of previously published theories.
