THURLER, Thalyta S. et al. Can factor analysis be applied to spectra taken in binary solvent mixtures?. J. Braz. Chem. Soc. [online]. 2009, vol.20, n.9, pp.1617-1624. ISSN 0103-5053. http://dx.doi.org/10.1590/S0103-50532009000900008.
It is suggested that, in spite the logical inconsistencies, factor analysis can be applied in many cases to fluorescence and absorption spectra of dyes in binary solvent mixtures. Limits as to when this application will be successful are derived. This idea was applied to four different dyes in two different binary solvent mixtures and was generally found to generate smoother curves, plotting the contribution of one of the two contributing bands to the experimental spectrum vs. solvent component mole fraction, as compared to those that are generated when one uses the normally applied method of plotting maximum peak position vs. solvent component mole fraction.
