The role of dielectric constantε of a solvent regarding its capability to dissolve ionized solutes was pointed out in Section 4.1 (the dielectric constant is typically given as the relative dielectric constant to vacuum). A higher dielectric constant of the solvent correlates with a higher ability...
Effective charge and dielectric constantElectrophoresis NMRPFG NMRDecreasing the dielectric constant of a mixed solvent results in a decreasing effective charge of the polyelectrolyte in solution, which in turn brings the polyelectrolyte to a more compact conformation, as seen from the reduced hydrodynamic...
Dependence of Ionic Mobility on Dielectric Constant of SolventBerns, D SFuoss, R M
The results showed that the relativedielectric constantof pork was decreased with increasing frequency, and the dielectric loss factor reached a minimum at 2500MHz. The relation between thedielectric constantof the solvent and the dissociation constant of Glycine was... ...
Dielectric Bridge The dielectric constant of solvents and solu- tions were measured by a transformer bridge (Ando Denki Co., Tokyo, Japan) in the frequency range from 300 to 3 MHz. A platinum con- centric cylinder with the air capacitance of 3.97 pF was used as a liquid cell and ...

In general, the dielectric constant is used as one factor representing the ease of polarization of a solvent. The dielectric constant of a solvent is determined as ∈=E/E0 wherein E is a potential difference between a pair of electrodes with the solvent therebetween when an electric field is...
Calculations are carried out to determine the relation between the dielectric constant of solutions of large charged particles and the charge distribution on the particles. It is shown that if the hydrodynamic forces cause the particles to rotate about a point fixed in each particle, the dielectric...
