The Russian Journal of Organic Chemistry, featured a study entitled, “Polarity and Vibrational Spectra of Bis (2-phenylethyl) – and Bis (2-phenylpropyl) phosphine Selenides”. The study used Brookhaven’s BI-870 Dielectric Constant Meter to measure the solution’s Dieletric permittivities of bis(2-phenylethyl)-phosphine selenide (I) and bis(2-phenylpropyl)phosphine selenide (II) in benzene and dioxane.
This study illustrated the dipole moments and vibrational spectra of the selenides and provided data of organophosphorus compounds having a P=Se bond.
Measuring of Dieletric Constants of a material is a method used by experts to determine relative permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability. Experts use specialized equipment to measure dielectric constants to ensure accurate data. Brookhaven Instruments’ BI-870 Dielectric Constant Meter is a simple and easy way to measure dielectric solvents including mixed liquids and solutions.
