摘要：
The microwave dielectric properties of aqueous solutions of potassium and cesium fluorides are studied over a wide concentration range at frequencies of 13 to 25 GHz and temperatures of 288, 298, and 308 K. The static dielectric constant epsilon(s) and the time tau and enthalpy of activation Delta H-epsilon(++) of dielectric relaxation for the solutions are calculated. It is demonstrated that, for fluorides, the disruptive effect of ions on the hydrogen bond network of water is weaker than that for the other halogenides.
