The analytical expression and the experimental curve of the exponential absorption spectrum of amorphous Se0.5S0.5 selenium-sulphur compound are compared. The parameters in the analytical expression for the exponential absorption spectrum, which determine the slope of the tails of the allowed bands, were found by fitting to the experimental curve. Using the DavisMott approximation, a new formula was obtained using the Kubo-Greenwood formula for the exponential absorption spectrum, which determines the density of electronic states at the tail of the conduction band. Using this formula and the exponential absorption spectrum determined experimentally, it is shown that it is possible to determine the density of electronic states at the tail of the conduction band.
