Experimental Study of the Magnetooptical Faraday Rotation Spectra in Some Aromatic Liquids

The magnetooptical properties of purified liquid phase of benzene, nitrobenzene, o-toluidine, o- anisidine, m-chloraniline and o-chloraniline were studied using Faraday effect measurements. Experimental results of Faraday rotation as a function of wavelength between 1.8 - 3.65 eV were obtained. It is shown that magneto-optical response of samples changes significantly with contents and geometry of substitution groups linked to the aromatic ring. Molecular-orbital theory semiempirical models were chosen to calculate electron spectra in visible and UV range to interpret experimental results of Faraday rotation spectra and explain influence of electron transitions to the mechanism of Faraday effect in aromatic liquids series.
