It is shown that the dipole moment of polar (water, methanol, formamide, acetone and acetonitrile) molecules in the neighborhood of a cation is increased primarily by polarization from the bare electrostatic charge of the cation, although the effective value of the latter is somewhat reduced by ...

The sudden shift of electrons causes a temporary polarity, drawing other, temporarily polar atoms having opposite charges. London dispersion forces are weak, but they show their strong influence in long molecules or molecules of high mass. The London dispersion forces are also known as induced ...

Learn about dielectric constant, dipole moment, and about polar and non-polar molecules and dielectric polarization in detail with BYJU'S.
This appendix defines thedipole momentand derives an expression for its magnitude as a function of distance and angle from the center of thedipole. Anelectric dipoleconsist of two equal charges,q+andq−, separated by a distanced, as shown inFigure 1.4.A1.1. These are typically molecules who...
A three-terminal cell for the dielectric measurement of liquid was made and the cell capacitance was determined using a capacitance bridge. The accuracy of the dielectric constant measurement with the apparatus was examined by measuring standard materials such as benzene and cyclohexane. The mean squar...
Related to Dipole moments:Molecular dipole moment dipole moment n. 1.The product of either charge in an electric dipole with the distance separating them. 2.The product of the strength of either pole in a magnetic dipole with the distance separating them. ...
aThis dipole moment causes water molecules to be attracted to each other (the slightly positive hydrogen side being attracted to the slightly negative oxygen side) and to other polar molecules. This attraction is named hydrogen bonding, and explains several of the water properties. 这偶极矩造成水...
The dipole moments of highly polar molecules measured in solution are usually smaller than the molecular dipole moments that are calculated with reaction field methods, whereas vacuum values are routinely calculated in good agreement with available vapor phase data. Whether from Onsager's theory (or ...
