different total polarisations shown by the same solute when dissolved in different solvents are to be related to alterations in the orientation polarisations (P) caused by replacement of one dielectric environment by another, the atomic and electronic polarisations being constant throughout such ...

The dielectric constant of water in presence of increasing concentrations of weakly protic solvents depressing the freezing point has been measured. The same measurements have been carried out for various volume ratios between 20°C and the freezing point, as well as in presence of glycine. The co...
as shown by several formulas inSections 4.1 and 4.2. The values of the dielectric constant for several common solvents at 25oC are given inTable 7.2.1. The dielectric constant also depends on temperature. As an example, the variation of the dielectric constant of water as a function of tempe...
By using complex numbers for the dielectric constant, we can specify the magnitude and phase. The values of the real part ε′ and imaginary part ε″ are related to the stored energy and the dissipation of energy within the medium, respectively. When surface plasmons exist, the real part of...
A general model has been developed for calculating the static dielectric constant of mixed-solvent electrolyte solutions. For mixtures of solvents without ... P Wang,A Anderko - 《Fluid Phase Equilibria》 被引量: 221发表: 2001年 On the computation of the coupled thermo-electromagnetic response of...

The dielectric constant values of some protic and aprotic solvents in pure state are presented on the basis of MSA method, perturbation theory and Cluster expansion formulation. The calculations are made on statistical mechanical basis considering the cooperative effect and formation of cluster by H-bo...
The metadata keys are presented in Table 3. Graphical representation of results In Fig. 3, we show a violin plot of the electronic and ionic contribution components of the dielectric constant for all calculated compounds, grouped according to the crystal system. Firstly, the plot shows that, as...
