Dynamics of the dielectric relaxation process in some dichlorotoluenes

The molecular dynamics of 2,6-, 2,4- and 3,4-dichlorotoluenes has been studied by measurements in the GHz region and in the temperature range 293–323 K of the real and imaginary parts of the complex dielectric permittivity in the pure liquid and in benzene solution. For all three isomers a single absorption band and a similar relaxation mechanism have been found both in the pure liquid and in solution. The results obtained have been interpreted according to the Debye model.
