摘要：

Lead bromide and lead chloride lattice dynamics studies by polarized IR reflectivity and Raman scattering are reported at room temperature and at 10 K. Reflectivity spectra from 20 to 300 cm-1 have been fitted with a model of the factorized form of the dielectric function. The lattice modes frequencies, damping factors and oscillators strengths are given, as well as the effective charges of the polar modes. The study concludes the ionic character of the compounds.
