In the frame of this work a group of chalcogenic glasses, arsenic and germanium sulfides and selenides were investigated. The structures and vibrational spectra of the unit elements of these materials, the so-called clusters, were calculated with quantum chemical methods. The yielded data were compared with the experimental spectra. It was established in this way which cluters exist really in these materials. The resulted data were analyzed with the tools of normal coordinate analysis and spectrum simulation. The sulfides and the selenides and from another point of view the arsenic and the germanium glasses were compared.
