Unusually rapid energy transfer and internal conversion in Xanthorhodopsin and its carotenoid antenna

Not Accessible

Your library or personal account may give you access

Abstract

Internal conversion and energy transfer from S2 of the salinixanthine antenna in xanthorhodopsin takes less than 30 fs, leading to lower singlets with rotated transition dipoles. This timescale questions models of resonant electronic energy transfer.
