Probing Instantaneous Single-Molecule Chirality in the Planar Ground State of Formic Acid

D. Tsitsonis, M. Kircher, N. M. Novikovskiy +12

We experimentally demonstrate that individual molecules of formic acid are chiral even when they are in the vibronic ground state, which has a planar equilibrium structure. We ioni…

Heavier chalcogenofenchones for fundamental gas-phase studies of molecular chirality

Manjinder Kour, Denis Kargin, Eileen Döring +15

Monoterpene ketones are frequently studied compounds that enjoy great popularity both in chemistry and in physics due to comparatively high volatility, stability, conformational ri…

Polarization and driving force analysis of coherent optical shear phonons in graphite

Christian Gerbig, Silvio Morgenstern, Ahmed S. Hassanien +4

Coherent optical phonons in the degenerate inter-layer shear mode of graphite launched by femtosecond laser pulses were investigated using ultrafast electron diffraction. The colle…

Excited state assignment and state-resolved photoelectron circular dichroism in chalcogen-substituted fenchones

Sudheendran Vasudevan, Steffen M. Giesen, Simon T. Ranecky +21

Excited electronic states of fenchone, thiofenchone, and selenofenchone are characterized and assigned with different gas-phase spectroscopic methods and \textit{ab initio} quantum…

Velocity Map Imaging Spectrometer Optimized for Reduction of Background from Scattered UV Light

Nicolas Ladda, Fabian Westmeier, Sagnik Das +10

Velocity map imaging spectroscopy is a powerful technique for detecting the momentum distribution of photoelectrons resulting from an ionization experiment on atoms or molecules. H…
