Internal conversion of the anionic GFP chromophore: in and out of the I-twisted S <sub>1</sub> /S <sub>0</sub> conical intersection seam

Abstract
The Z – E photoisomerization quantum yield of the HBDI − chromophore is a result of early, non-statistical dynamics around a less reactive I-twisted intersection and later, statistical behavior around the more reactive, near-enantiomeric counterpart.
