摘要
We present a theoretical study for the reflectance anisotropy of porphyrin layers deposited onto gold substrates by Langmuir-Schaefer technique. We have obtained reflectance anisotropy spectra as function of the number of porphyrin layers, and show that the line shape goes from peak-like to derivative-like as the geometrical arrangement of the porphyrin molecules is changed. Our results coincide qualitatively with those of the experiments. (C) 2003 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
