Abstract

The spectra of dipole-active optical phonons are measured for the cubic and orthorhombic phases of PbF2 single crystals. The frequencies and eigenvectors of normal modes in the Pnma orthorhombic phase are calculated. It is found that the spectrum of the cubic phase exhibits excess vibrational modes of the PbF2 orthorhombic phase.
