摘要：
A dispersion analysis of reflectance spectra of CdP2 crystals was performed and the dispersion parameters were obtained in the far infrared region (FIR) at different temperatures for the first time. Dielectric permittivity was obtained for the polarization along the a- and c-axes of a single crystal. Phonon modes are described by their oscillator parameters, i.e. the frequency, oscillator strength and the damping constant. Temperature dependence of these parameters is discussed.
