摘要：

A refined version of the "principal-component analysis-self-modeling" (PCA-SM) method was applied to resolve the fluorescence spectra of mixtures of rotamers for two trans-1,2-diarylethylenes. The effect of the excitation wavelength (lambda(exc)) on the fluorescence of 3-styrylphenanthrene allowed the photophysical and thermodynamic parameters of the two rotamers to be obtained. The effect of lambda(exc) and temperature on the emission of 2-styrylanthracene gave similar information for a three-component system (two rotamers, one having a dual fluorescence). Comparison with results previously obtained by the kinetic fluorescence analysis (KFA) method was useful for checking the validity of the statistical and kinetic methods and led to some extensions and some revisions of the already published data.
