Description
Summary:The authors present a method of the interactive computer-assisted analysis of the rotational diffusion fluorescence experiments aimed at determining the hydrodynamic shapes of molecules in solutions. Constraints resulting from the monoexponential analysis of experimental emission anisotropy decay as well as from the quantum-chemical calculations, allow to discriminate between competing models of the anisotropic rotation. This procedure should be applied as an initial stage in the process of the experimental data analysis. The utility of the proposed method is demonstrated for 3,9-dibromoperylene in glycerol.
