英文摘要: Abstract(#br)The physical mechanism responsible for Faraday rotation (FR) in magnetic molecules under the irradiation of visible light is under intense investigations. In this paper, a quantum mechanical description of the Faraday rotation is provided based on the electronic transitions between the molecular states. The method is applied on bis[tetrachloroferrate(III)]chloride magnetic molecule showing significant FR under irradiation of the visible light ( λ = [ 450 , 775 ] nm ) at room temperature. Use of dielectric tensor for the molecule in terms of oscillator strengths between HOMOs (highest occupied molecular orbital) and LUMOs (lowest unoccupied molecular orbital) leads to magnetization curve as a function of frequency. The results are obtained in view...
