The effect of electron-induced dichroism was observed in amorphous chalcogenide glasses based on As$_2$S$_3$ obtained by the traditional method of direct synthesis. For the investigation we used a cube of glass with the edge nearing 8 mm irradiated by accelerated electrons ($E=2.8$ MeV). A microstructural mechanism of the electron-induced dichroism in the glassy As$_2$S$_3$ was studied using the differential IR Fourier-spectroscopy techique. Plates of the cubic sample with normal parallel unit ($\parallel$) and perpendicular to the accelerated electron beams ($\perp$) were chosen as the investigated ones in our experiment.

It was shown in accordance with the differential spectra (obtained at the termoannealing of temperature differences of both the components of reflectivity ($Δ R_{\parallel}(ν)$ and $Δ R_{\perp}(ν)$) that coordination defects were being formed at the electron irradiation. A classification of the investigated coordinating defects in the amorphous chalcogenide glasses created by the accelerated electron is presented.
