It is a particularly challenging task in stereochemistry to determine the absolute configuration of chiral molecules, i.e. to assign to a given sample the microscopic enantiomeric structure. In recent years, Coulomb Explosion Imaging (CEI) has been s

X-ray as well as electron diffraction are powerful tools for structure determination of molecules. Studies on randomly oriented molecules in the gas-phase address cases in which molecular crystals cannot be generated or the interaction-free molecular

Prochiral formic acid has been enantioselectively driven to chiral fragmentation, leading to photoion circular dichroism in the molecular frame.
Chirality is omnipresent in living nature. On the single molecule level, the response of a chiral sp
