Study of Magneto-Optical Properties of Aromatic Liquids and Their Application in Signal Processing

Experimental Faraday rotation spectra in the range of 1.8–3.65 eV were recorded for H2O, CCl4, dimethylaniline, benzene, nitrobenzene, o-toluidine, o-anisidine, m-chloroaniline, and o-chloroaniline. Semiempirical quantum mechanical self-consistent field (SCF) calculations using the MNDO/D method for organic molecules were chosen to evaluate electronic spectra in the visible range for interpretation of experimental results. It was shown that the magneto-optical response of samples not only varies depending on the geometry of the distribution of π electrons in aromatic liquids, but also significantly depends on their chemical composition.
