The methods of broadband dielectric spectroscopy are used to study the effect of substitution of Fe^3+ by Sc^3+ in Pb(Fe_1 – _ x Sc_ x )_2/3W_1/3O_3 solid solutions of perovskite family on the dielectric response function in the frequency range from 120 Hz up to 100 THz (4 × 10^–9–3 × 10^3 cm^–1). The experimental data are analyzed in the framework of multiparameter dispersion models. The evolution of the dispersion parameters of absorption bands depending on the degree of cation substitution in the B position of perovskite basis of ABO_3 is discussed.
