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…
Exploiting correlations in multi-coincidence Coulomb explosion patterns for differentiating molecular structures using machine learning
Anbu Selvam Venkatachalam, Loren Greenman, Joshua Stallbaumer +3
Coulomb explosion imaging (CEI) is a powerful technique for capturing the real-time motion of individual atoms during ultrafast photochemical reactions. CEI generates high-dimensio…
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…
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…
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…
