Abstract
The lattice dynamics of the fluoride scheelite CaZnF4 have been investigate d by means of infrared reflectivity and Raman scattering. The measured phon on modes have been assigned to the various irreducible representations of t he point group of the crystal. The phonon dispersion curves, density of sta tes and sound velocities have been calculated within a rigid-ion model base d on experimental zone-centre phonons.
