✦ Synopsis

An analysis is made of the magnitude of distortions in the measured absorbance, circular dichroism, optical rotation, and other spectral properties of cylindrical structures based on Duysens' description of the absorbance flattening phenomenon. The model calculations are made for isotropic particles having the same refractive index as the solvent. Exact integral expressions for coefficients relating optical properties of chromophores in cylindrical particles with those of isolated chromophores in solut.ion are obtained for cylinders of any radius and height which have either random or perpendicular orientation with respect to the incident radiation. The results of numerical evaluation of the integrals for specific cases are presented to demonstrate the dependence of flattening on cylinder height, radius, extinction coefficient, and orientation.
