Correlation among solvent polarity scales, dielectric constant and dipole moment, and a means to reliable predictions of polarity scale values from current data - Griffiths, Pugh - 1979 () Citation Context ...olubility parameter of the solvent on extract yield and diterpenoid lactones extracted from...
2.2Dielectric Constant Thedielectric constantexhibits the liquid polarity, and it is of primary importance for the evaluation of the solvent properties of water. Generally, the dielectric constant can be defined as the ratio of theabsolute permittivityof a substance to the absolutepermittivity of free...

Effects of electronics, aromaticity, and solvent polarity on the rate of azaquinone-methide-mediated depolymerization of aromatic carbamate oligomers. for creating aromatic poly(carbamates) that depolymerize from head-to-tail in low dielectric constant environments when exposed to specific applied signals...
The excluded volume effect and the influence of solvent polarity on the relaxation strength of the "dielectric normal mode process" originating from fluctuation of the end-to-end distance were investigated on dilute solutions of poly(2,6-dichloro-1,4-phenylene oxide) (PDCPO) in various solvents...
The capacitance Cx in a condenser filled with a particular material is determined by dividing it by C0, where ε is the dielectric constant. Dielectric constants represent a solvent's ability to sustain a charge separation during its dissolution. ...
Because of a sharp decrease in its dielectric constant, water loses its polarity when brought to the supercritical conditions and its properties starts to ... RO Can?Az,C Erkey - 《Chemical Engineering Research & Design》 被引量: 22发表: 2014年 ...
CONSIDERABLE attention is at present being focused on the effect of solvent environment on infra-red frequencies 1–3 . The early dielectric constant treatment of Kirkwood, Bauer and Magat 4 (KBM), long known to be inadequate for the group frequencies which had been studied in any detail, ...
Polarizability is the capacity of the solvent to induce any kind of electrostatic interaction with a dissolved solute, which is a measure of the “polarity” of the solvent. Hence, polarizability is a macroscopic property just like the dielectric constant. Using the Kamlet–Taft solvatochromic method...
