The dynamics of the electron subsystem parameters in In<sub>0.5</sub>Tl<sub>0.5</sub>I substitutional solid solutions has been studied theoretically using of the pseudopotential method. According to Kramers-Kronig method there have been determined the optical functions of the multilayer In0,5Tl0,5I for the different light polarizations in a broad energy range (0 - 15 eV). The energies of oscillators were defined from the Argand diagrams. The main oscillator settings transitions has been determined.Keywords: substitutional solid solutions, dielectric function, oscillator, Argand diagrams, polarization.
