Abstract

Using a simple model system consisting of chl a, chl b and their mixtures in an oriented LC matrix, it is shown that PAS provides information concerning excitation energy transfer and formation of aggregates in addition to that provided by fluorescence measurements. Such information could be valuable especially in case of biological light scattering samples for which the fluorescence measurements are strongly perturbed.
