Ultrafast Raman Observation of the Perpendicular Intermediate Phantom State of Stilbene Photoisomerization

Joint press release (in Japanese)

photoisomerization is generally described by a model in which the reaction proceeds via a common intermediate having a perpendicular conformation around the rotating bond, irrespective of from which isomer the reaction starts. Nevertheless, such an intermediate has yet to be identified unambiguously, and it is often called the ‘phantom’ state. Here we present the structural identification of the common, perpendicular intermediate of stilbene photoisomerization using ultrafast Raman spectroscopy. Our results reveal……
