In transient spectroscopy studies we find such high performance blends to demonstrate an oscillatory signature, with a period which matches a Raman mode. DFT calculations indicate that this is a breathing mode of a donor polymer. Thus vibronic coupling, coupled electronic and vibrational coherence, could assist in the charge separation process generating free charges from excited states in donor/acceptor junctions.
