Abstract : In the report the absorption of infrared rays by nonideal ion crystals is discussed. In the calculation it was assumed, that the power constants of the crystal do not change when an atom of an ideal lattice is replaced by an admixture atom. The form of the basic absorption band of a nonideal crystal and the integral contribution of local frequencies were determined. The width of the curve of the basic absorption band and the integral contribution of local frequencies were determined in the first order by concentration. The calculations indicate a possible quasi-resonance expansion of the basic absorption band. (Author)
