Abstract : A Twin-T bridge was used to investigate the dielectric behavior of five solid solutions of n-dodecyl ether. (C12H25)2O, in n-hexacosane, C26H54, in the frequency range 0.6-30 mc. An RX meter was being used to measure solid solutions of lauryl laurate, C12H25CO2C11H23, in hexacosane in the range 0.5-250 mc. The variety of solid phases encountered complicates the behavior observed. Preliminary measurements on benzophenonetetrahydrofurane mixtures could be analysed in terms of two relaxation times. To investigate the simple dipolar mixtures further, mixtures of 2-chloronaphthalene in pyridine, 4-iodobiphenyl in chloroform, benzophenone in pyridine, and benzophenone in chloroform were measured at wave lengths of 575 m, 10 cm, 3.2 cm, 1.2 cm, and 2.2 mm. The dispersion region of each mixture could be represented by superposition of two Debye relaxation processes with the relaxation times. The larger relaxation time characterises the orientation of the solute molecule and the smaller the orientation of the solvent molecule. The relative weights of the two dispersion regions were proportional to the square of the dipole moment and the number of molecules of the respective components present.
