Title: Femtosecond fluorescence depletion anisotropy: Application to the B850 antenna complex of Rhodobacter sphaeroides

Abstract

The authors extend the technique of fluorescence depletion to measure femtosecond anisotropy decays. In cases where excited-state absorption contributes to the transient spectra, such as in photosynthetic antenna complexes, the anisotropy measured by fluorescence depletion differs from that measured by pump-probe spectroscopy. This new technique has the potential to elucidate the fate of the states created by excited-state absorption.
