Elucidating Norrish Type-I reactive pathways by ultrafast X-ray absorption spectroscopy
Martin Graßl, Pablo Unzueta, Andreas E. Hillers-Bendtsen +20
Norrish type I reactions selectively cleave carbon-carbon bonds directly adjacent to carbonyl groups. Despite their broad use in combination with aromatic carbonyls for additive ma…

Advanced Control of Electron Beams: Tailoring X-ray Production with Programmable Laser Shaping
Jack Hirschman, Randy Lemons, Hao Zhang +23
Leveraging the full scientific capabilities of next-generation high-repetition-rate free-electron lasers requires programmable control over electron-beam properties at their source…

Probing ultrafast ππ*/nπ* internal conversion in organic chromophores via K-edge resonant absorption
T. J. A. Wolf, R. H. Myhre, J. P. Cryan +21
Organic chromophores with heteroatoms possess an important excited state relaxation channel from an optically allowed ππ* to a dark nπ*state. We exploit the element and site specif…
