Abstract
We show that the terahertz (THz) frequency spectra of powdered ionic crystalline systems are not described by their infrared active phonon modes alone. Instead, it is necessary to include the coupling of the phonon modes with the macroscopic electric field generated by the collective displacement of the vibrating ions.
