Absorption and fluorescence spectra of the meso and racemic diastereoisomers of 2,4-di( 2-pyrenyl)pentane (ZDPP) which form intramolecular excimers in methylcyclohexane at 25°C are presented. From time-correlated single-photon counting measurements of the double-exponential monomer and excimer fluor
