(Graph Presented) Dispersion of the Verdet constant is determined experimentally and theoretically for benzene, toluene, and p-xylene as pure liquids. Both theory and experiment show that the amplitude of the Verdet constant decreases when methyl groups are added to the benzene ring, due to the decreasing number density with the increasing size of the molecule. The picture shows the Verdet constants of benzene, toluene, and p-xylene as a function of wavelength and compares theory with experiment.
