Neural Network Based Molecular Structure Retrieval from Coulomb Explosion Imaging Data
Amirhossein Ghanaatian, Aravinth K. Ravi, Joshua Stallbaumer +6
Determining the structure and following the structural evolution of molecules undergoing chemical reactions is one of the key goals of ultrafast molecular physics and chemistry. Re…
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…
Rotational coherences in O following strong-field ionization
Huynh Van Sa Lam, Tomthin Nganba Wangjam, Vinod Kumarappan
We investigate the wave packet that remains bound in the ground and excited cationic states of oxygen after strong-field ionization by an intense 800-nm pulse. Much weaker probe pu…
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…
