The Dielectric Constant, or permittivity – ε – is a dimensionless constant that indicates how easy a material can be polarized by imposition of an electric field on an insulating material. The constant is. the ratio between the actual material ability to carry an alternating current to the ability of vacuum to carry the current

Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O. This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high melting point.

In chemistry, a protic solvent is a solvent that has a hydrogen atom bound to an oxygen (as in a hydroxyl group), a nitrogen (as in an amine group) or a fluorine (as in hydrogen fluoride). In general terms, any solvent that contains a labile H + is called a protic solvent.

goal of this paper is to investigate the dielectric relaxation in the DMSO/water mixtures in hope of better understanding the dielectric mechanism of this system. Along these lines, it is also interesting to investigate the dielectric relaxation of highly concentrated DMSO solutions, since dimethyl sulfoxide is a self-associating liquid.
