Paper Abstract

The dielectric parameters of monocrystalline LiF and CaF2 were measured at wavenumbers between 1 cm-1 and 40 cm-1 by dispersive Fourier transform spectroscopy and Fabry-Pèrot resonators. The results are discussed in the framework of an one-phonon absorption model. Its shown that the parameters of the transverse optical phonon absorption band can be taken for an approximate assessment of the measured dielectric data.
