Dielectric relaxation phenomena of alkyl acrylate on complexation with phenol dissolved in carbon tetrachloride under static and high frequency electric field

Abstract

Double relaxation times ₂ and ₁ due to whole molecular rotation and the flexible parts of the binary (jk) polar mixture of alkyl acrylate (j) and phenols CCl₄ (i) at 35ᵒC are estimated using susceptibility data under 9.37 GHz electric field. Five systems out of twelve exhibit ₂, ₁ and µ₂, µ₁. ₂’s of all systems show gradual increase with the chain length of esters offering hindrance to the rotation of the molecule. The relative contributions c₁ and c₂ due to ₁ and ₂ for five systems in terms of and curve at are estimated along with symmetric _s, characteristics _cs establishing the symmetric distribution of relaxation behavior. The estimated µ's and ₂'s agreed with the reported and measured values. The solute-solute and solute-solvent molecular associations through H-bonding are also as certained.
