Abstract
Analytical equations for coefficients of dielectric permeability ε1(ω) and dielectric losses ε2(ω) of electrolyte solutions are obtained, based on the relationship between complex dielectric permeability and specific conductivity coefficients. The region of frequency dispersion is considered for dynamic dielectric permeability coefficient ε1(ω) of an aqueous NaCl solution. Friction coefficients βa and βb, relaxation times τa, τb, and τab, and dielectric permeability coefficient ε1(ω) are numerically calculated for selected intermolecular interaction potentials \({\Phi _{ab}}(\left| {\bar r} \right|)\) and equilibrium radial distribution functions \({g_{ab}}(\left| {\bar r} \right|)\) over a wide range of variation in density ρ, concentration c, temperature T, and frequencies ω. The theoretically calculated results for ε1(ω) are found to be in quantitative agreement with experimental data.
