RM Adar,T Markovich,A Levy,H Orland,D Andelman 摘要: The dielectric constant of ionic solutions is known to reduce with increasing ionic concentrations. However, the origin of this effect has not been thoroughly explored. In this paper we study two such possible sources: long-range Coulombic ...
The Dielectric Constant of Solutions of Dipolar Ions. Jeffries. Wyman 被引量: 0发表: 0年 Dielectric constant of dipolar hard sphere mixtures The dielectric constant of dipolar hard sphere mixtures is calculated from the analytic solution of the mean spherical approximation (MSA) and using Monte ....
The static dielectric constant of solutions of water in n -alcohols at 15, 25, 35, and 45°C[J] . Alessandro D’Aprano,Dorina I. Donato,Eugenio Caponetti.Journal of Solution Chemistry . 1979 (2)A. D’Aprano, D. Donato and E. Caponetti, J. Solution Chem., 8 , 135 (1979). ...
This is shown by the divergent results obtained when different types of detection are employed and leads to the conclusion that the change in dielectric constant of such solutions as observed by this method depends more or less upon the characteristics of the particular generating and receiving ...
The effect on the dielectric constant and refractive index of weak complex formation between the components of a binary solution is calculated. Equations are developed which relate the deviations from additivity of the molar polarization and the molar refraction at infinite wavelength to the equilibrium...
For example, pure ice has a dielectric constant of 3.2 and loss factor of 0.003 at 0 °C while liquid water at the same temperature has an ε′ of 79 and an ε″ of 21. As can be seen in Figs. 1 and 2, the higher the moisture content, the more dramatic the change in ...
dielectric constant of the solvent also affects interactions in solution that involve ions andpolar molecules, decreasing the intermolecular energy when the dielectric constant increases, as shown by several formulas inSections 4.1 and 4.2. The values of the dielectric constant for several common ...
