We have constructed an apparatus with the circuit of a dynatron oscillator suitable for the measurement of the dipole moment in the solution and measured those of hydroquinone dimethylether in various solvents. From these measurements it was found that the dipole moments of hydroquinone dimethylether increased in the order of its solutions in benzene, carbon tetrachloride and petroleum ether, while those of anisole decreased in the same order. It seems evident from these observations that the chnanges of electron migration effects in various solutions play an important role in the solvent effects on the dipole moment of anisole. Further we have studied on the relations between electron migration effects and near ultraviolet absorption spectra of benzene, anisole and hydroquinone dimethylether. Agreement between calculated energy levels and observed values is fairly good.
