Etude de la relaxation moleculaire des amines a travers la densite spectrale

Abstract

The “spectral density” I(ω) computed for the Cole Davidson model of dielectric dispersion reveals the asymetric distribution of molecular relaxation times. The linearity between the expression ωI(ω) and the dielectric absorption ε″ does not appear. This experimental study for the primary amines (propylamine to dodecylamine) is in good agreement with the introduced theory.
