Time-Resolved Chiral X-Ray Photoelectron Spectroscopy with Transiently Enhanced Atomic Site Selectivity: A Free-Electron Laser Investigation of Electronically Excited Fenchone Enantiomers

Abstract

A soft x-ray probe reveals the contribution of specific atoms in the compound fenchone to the molecule's overall chirality following photoexcitation, paving the way for broader studies of chirality during ultrafast reactions.
