Davydov Splitting Without a Davydov Pair and Highly Mobile Singlet Excitons in Perylene Red Microcrystals
Chris Rehhagen, Tolibjon Abdurakhmonov, Magnus Frank +2
We investigate the excitonic properties of perylene red microcrystals, whose unit cell contain eight molecules, using both experimental and theoretical methods. Only two of the nom…

Site-selective and real-time observation of bimolecular electron transfer during photocatalytic water splitting
Alexander Britz, Sergey I. Bokarev, Tadesse A. Assefa +13
Time-resolved X-ray absorption spectroscopy has been utilized to monitor the bimolecular electron transfer in a photocatalytic water splitting system for the first time. This has b…
