✦ Synopsis

Empirical formulae for evaluating the dielectric relaxation intensity, or the magnitude of dielectric dispersion, from dielectric loss data, proposed by Kita and Koizumi, in a limited range of frequency around the relaxation frequency for the Davidson -Cole relaxation has been verified in the case of three i-alkyl halides. The relaxation intensity As is expressed in terms of E;l ' the dielectric loss maximum and !J the frequency separation for a half, fwo thirds or three quarters of G ' in the form n As =E" 3 M /[r + '2 + c3w 1 where the numerical constants C 1,C2 and C3 are given for the respective types of relaxation.
