Low and High Frequency Vibrations Synergistically Enhance Singlet Exciton Fission Through Robust Vibronic Resonances

Atandrita Bhattacharyya, Amitav Sahu, Sanjoy Patra +1

Singlet exciton fission (SEF) is initiated by ultrafast internal conversion of a singlet exciton into a correlated triplet pair (TT)1. The `reaction coordinates' for ultrafast SEF…
