“…To overcome this difficulty corrected solvation numbers were calculated (5,6,12,35,45) based on the superposition of kinetic depolarization and dielectric saturation. The result is reasonable for aprotic (12) but not convincing for protic solvents.…”

“…Direct access to molecular motions is given vLa. the autocorrelation function of the molecular dipole moment (t) (t) = (14) or the corresponding microscopic (or molecular) relaxation time (t) can be related to Fp with the help of a complicated procedure, due to the long range dipolar interaction forces of the molecules. For details of calculation reference is made to the literature (1,64).…”

-High frequency permittivity of non-aqueous electrolyte solutions and their solvents is discussed in the framework of time domain and frequency domain methods. Evaluation of data is performed on the basis of models presupposing one or more relaxation processes. Depression of the solvent permittivity, relaxation times of the solvent molecules, and dispersion amplitudes and relaxation times of ion-pair relaxation are investigated with regard to actual theories underlying these phenomena. Information is obtained on structural and dynamical properties of classes of electrolyte solutions based on rotic H-bonding, dipolar aprotic, and low permittivity solvents and mixtures of solvents.
