Is Photoelectron Circular Dichroism Sensitive to Helical Chirality? The Paradigm of Gas-Phase Carbo[6]Helicene.
The first member of helically chiral helicenes - carbo[6]helicene (or hexahelicene) - exhibiting sufficient enantiomeric stability under supersonic jet conditions, was studied by photoelectron circular dichroism (PECD) using circularly polarized vacuum ultraviolet synchrotron light and a double imaging photoelectron-ph...
