Probing the structure of cyclic hydrocarbon molecules with X-ray-induced Coulomb explosion imaging
Kurtis D. Borne, Rebecca Boll, Thomas M. Baumann +27
Coulomb explosion imaging (CEI) is a powerful experimental technique that maps a molecule's geometric structure onto the momenta of ionic molecular fragments produced by rapid mult…
Imaging transient molecular configurations in UV-excited diiodomethane
Anbu Selvam Venkatachalam, Huynh Van Sa Lam, Surjendu Bhattacharyya +6
Femtosecond structural dynamics of diiodomethane () triggered by ultraviolet (UV) photoabsorption at 290 nm and 330 nm are studied using time-resolved coincident…
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…
Simultaneous imaging of vibrational, rotational, and electronic wave packet dynamics in a triatomic molecule
Huynh Van Sa Lam, Van-Hung Hoang, Anbu Selvam Venkatachalam +9
Light-induced molecular dynamics often involve the excitation of several electronic, vibrational, and rotational states. Since the ensuing electronic and nuclear motion determines…
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…
