Description

Femtosecond X-ray solution scattering (XSS) has enabled us to capture photoinduced structural dynamics in solvated transition metal complexes with atomic-scale resolution, revealing intramolecular changes, vibrational coherences, and solvation dynamics. In this talk, I will present recent XSS results from the LCLS, with a particular emphasis on tracking photoinduced solute–solvent hydrogen-bond rearrangements coupled to ultrafast electron transfer (Nature Chem. 13, 343–349, 2021). I will also discuss opportunities for probing chemical dynamics in solution using ultrafast electron diffraction (UED), highlighting insights from the photodissociation of tri-iodide studied at the LCLS MeV-UED instrument (Struct. Dyn. 7, 064901, 2020).
