Sažetak

The polarized far-infrared spectra and nonpolarized Raman spectra of ternary sulphide SnGeS3 are presented in the range from 20 to 450 cm-1. 22 IR and 20 Raman modes of SnGeS3 are observed. Using a Kramers-Kronig analysis, the optical constants and dispersion relation were obtained. A factor group analysis has been performed to identify the symmetries of the observed modes. The discussion on the vibrational properties is given with respect to the crystal structures of SnGeS3 (the chains of GeS4 tetrahedra which are linked together by sharing corners).
