Congratulations on the acceptance of the manuscript “Unveiling ultrafast dynamics in bridged bimetallic complexes using optical and X-ray transient absorption spectroscopies.” Brian Phelan, Tae Wu Kim, Darren Hsu, and Pyosang Kim from our research group contributed to this work led by Michael Mara. This work shows how vibronic coupling between transition metal centers (Cu/Os) affects the ultrafast dynamics in bridged multi-metallic systems, presenting avenues for tuning charge-transfer states through judicious choice of metal/ligand groups.
