Abstract
The quenching of Chlorophyll triplets by triplet energy transfer (TET) to carotenoids is one of the photoprotection strategies in photosynthetic organisms, and prevents singlet oxygen formation. Here we present the study of TET rates in a minor light-harvesting complex (LHC) of higher plants, using a fully atomistic strategy that combines a molecular dynamic simulation a polarizable quantum/classical calculation. We find that structural fluctuations of the LHC can largely enhance the TET rates, which are in the sub-nanosecond scale, in agreement with experimental findings.
