| Abstract: | Essentially distortion-free imaginary dielectric index spectra have been obtained for LiF from Kramers-Kronig (KK) dispersion analysis of I.R. reflectance data at 300 K, 80 K and 20 K. The frequency dependence of the damping function as well as the temperature dependence of the various dispersion parameters of the first transverse optic mode have been illustrated. The effective damping constant ggo, and the resonance frequency νo, are found to be in satisfactory agreement with the theoretical calculations. |
