Abstract
The complex dielectric permittivity of ortho-, meta-, and para-chloroaniline has been measured at various temperatures at the wavelengths of 10, 3, 2, and 1 cm. For the first two compounds the measurements have been made in pure liquid from as well as in solutions in carbon tetrachloride at various concentrations. p-Chloroaniline has been measured only in dilute solution form. The results have been analyzed in terms of two relaxation times, attributed to the rotation of the entire molecule and to the inversion of the NH2 group. Evidence for the self association of the molecules through weak hydrogen bonding has been indicated.Keywords
