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 ... PT Cummings,L Blum - 《Journal of Chemical Physics》 被引量: 178发表: 1986年 ...
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 correlations and solvent excluded-volume. Correlations origina...

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...
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 ...
Dielectric Constant of AN Electron-Free T1+ I- Plasma 来自 AIP Publishing 喜欢 0 阅读量: 35 作者: Davidovits,P. 摘要: Measurements are reported of the frequency‐dependent complex impedance of a capacitor filled with thallium iodide vapor, photodissociated into T1+and Ito form an electron‐...
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 ...

Impedance spectroscopy is an effective method to investigate the dielectric properties of powders by dispersing particles in proper liquids. It allows reliable calculation of the dielectric constant by analysis of impedance spectra for a variety of particulate materials. The temperature dependence of the ...
