X-ray Driven Trihydrogen Formation on Silica Nanosurfaces
Samuel Sahel-Schackis, Adam Summers, Ritika Dagar +29
The trihydrogen cation () initiates the ion-molecule reactions that build molecular complexity in interstellar space. Whether its canonical formation reaction, $\ma…
Elucidating Norrish Type-I reactive pathways by ultrafast X-ray absorption spectroscopy
Martin GraÃl, 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…
Imaging valence electron rearrangement in a chemical reaction using hard X-ray scattering
Ian Gabalski, Alice Green, Philipp Lenzen +24
We have observed the signatures of valence electron rearrangement in photoexcited ammonia using ultrafast hard X-ray scattering. Time-resolved X-ray scattering is a powerful tool f…
Imaging the Photochemistry of Cyclobutanone using Ultrafast Electron Diffraction: Experimental Results
A. E. Green, Y. Liu, F. Allum +27
We investigated the ultrafast structural dynamics of cyclobutanone following photoexcitation at nm using gas-phase megaelectronvolt ultrafast electron diffraction. Our inv…
