Characteristics of the discrete vibration levels of substitution impurity are calculated for frequencies belong to gap between acoustic and optical zones (deuterium in PdH) as well as for the areas outside the phonon spectra (hydrogen in PdD). Data of neutron diffraction analysis are used to determine the force constants of pure palladium as well as PdH solid solutions. Diverse configurations of vacancies close to impurity atoms are discussed. With the help of the calculated frequencies and intensities of the local and gap vibrations in the system isotope-defect + vacancies it is possible to analyze behavior of the certain characteristics in disordered solid solutions PdH(D)x<1 and to obtain information about the vacancy structure of the considered compounds.
