dc.description.abstract	Reflectivity spectra of Tl3SbS3, Tl3AsS3, and Tl3AsSe3 crystals have been investigated in the wave number range 50–600 cm−1 for the polarizations E∥c and E c. The fundamental phonon parameters, the limiting dielectric constants ϵ∞ and ϵS and the reflectivity spectra contours have been calculated by using classical dispersion relations for both E∥c and E c configurations. The Szigeti effective charges and the relative ion charges of As, Tl, Sb, Se, S anions and cations have been calculated in dependence on the incident light polarization.	en_US
