Heteroatom Position Controls Ultrafast Photodynamics of Oxazole and Isoxazole
Briony Downes-Ward, Paul Javed, Huynh V. S. Lam +27
The ultrafast photochemistry of heterocyclic compounds is central to photobiology and materials chemistry, yet direct experimental observation of their structural dynamics remains…
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 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 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 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 inve…
Differentiating Three-Dimensional Molecular Structures using Laser-induced Coulomb Explosion Imaging
Huynh Van Sa Lam, Anbu Selvam Venkatachalam, Surjendu Bhattacharyya +8
Coulomb explosion imaging (CEI) with x-ray free electron lasers has recently been shown to be a powerful method for obtaining detailed structural information of gas-phase planar ri…
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…
X-ray Coulomb explosion imaging reveals role of molecular structure in internal conversion
Till Jahnke, Sebastian Mai, Surjendu Bhattacharyya +26
Molecular photoabsorption results in an electronic excitation/ionization which couples to the rearrangement of the nuclei. The resulting intertwined change of nuclear and electroni…
Monitoring the evolution of relative product populations at early times during a photochemical reaction
Joao Pedro Figueira Nunes, Lea Maria Ibele, Shashank Pathak +31
Identifying multiple rival reaction products and transient species formed during ultrafast photochemical reactions and determining their time-evolving relative populations are key…
Time-Resolved Coulomb Explosion Imaging Unveils Ultrafast Ring Opening of Furan
Enliang Wang, Surjendu Bhattacharyya, Keyu Chen +10
Following the changes in molecular structure throughout the entirety of a chemical reaction with atomic resolution is a long-term goal in femtochemistry. Although the development o…
