Abstract / Description:We demonstrate an experimental method to record snapshot diffraction images of polyatomic gas−phase
molecules, which can, in a next step, be used to probe time−dependent changes in the molecular
geometry during photochemical reactions with femtosecond temporal and angstrom spatial resolution.
Adiabatically laser−aligned
1−ethynyl−4−fluorobenzene (C8 H5 F) molecules were imaged by diffraction of photoelectrons with
kinetic energies between 31 and 62 eV, created from core ionization of the fluorine (1s) level by
≈80 fs x−ray free−electron− laser pulses. Comparison of the experimental photoelectron angular
distributions with density functional theory
calculations allows relating the diffraction images to the molecular structure
