Abstract

Fluorescence upconversion experiments and ab initio calculations show that S2-Qx electronic excitation transfer (to several Bchl Qx transitions) is the primary pathway for carotenoid to Bchl energy transfer. Calculations on a carotenoid-B850-B850 aggregate suggest that the carotenoid may mediate B800-B850 EET by modifying the B850 transition density.
