Experimental and Theoretical Aspects of Higasi's Equation for a Quick Determination of Electric Dipole Moment in Solution

Abstract

In the present investigation the authors have determined the electric dipole values for twenty-three organic solutes according to Higasi's method. Except for two substances, viz., iodoform and ethylene dibromide, the dipole values so obtained agree fairly well with those obtained by usual methods. A reassessment of Higasi's equation has been made on theoretical grounds and a more general equation has been obtained.

“…The dipole moment was also evaluated from Higasi's simple formula, for benzene solvent at 25' (22,23).…”

Determination of the Dielectric Constant of Nanoparticles. 1. Dielectric Measurements of Buckminsterfullerene Solutions

“…The “solvent effect” makes the value of the polarization obtained by extrapolation to infinite dilution not equal to estimates obtained by measurements of isolated molecules in the gas phase. Several theoretical models have been put forth to explain the effect by “self-consistent” modifications of mean-field theory and by accounting for the solvent geometry. , Experimental procedures have been developed to minimize the errors due to the solvent effect. − This situation then brings us to an important question. Are nanoparticles large enough to be reasonably described by continuum theory or do these materials lead to the same problems as found for molecular dispersions?…”
