Abstract

state, yielding an overall transfer efficiency of 94%, in excellent agreement with previous reports. We propose that the observed structural distortions of spheroidene dynamically enhance coulombic coupling with surrounding bacteriochlorophylls, which may underlie the remarkably high efficiency of excitation energy transfer.
