abstract = {Following structural dynamics in real time is a fundamental
goal towards a better understanding of chemical reactions.
Recording snapshots of individual molecules with ultrashort
exposure times is a key ingredient towards this goal, as
atoms move on femtosecond (10$< {−15}$ s) timescales.
For condensed-phase samples, ultrafast, atomically resolved
structure determination has been demonstrated using X-ray
and electron diffraction. Pioneering experiments have also
started addressing gaseous samples. However, they face the
problem of low target densities, low scattering cross
sections and random spatial orientation of the molecules.
Therefore, obtaining images of entire, isolated molecules
capturing all constituents, including hydrogen atoms,
remains challenging. Here we demonstrate that intense
femtosecond pulses from an X-ray free-electron laser trigger
rapid and complete Coulomb explosions of 2-iodopyridine and
2-iodopyrazine molecules. We obtain intriguingly clear
momentum images depicting ten or eleven atoms, including all
the hydrogens, and thus overcome a so-far impregnable
barrier for complete Coulomb explosion imaging—its
limitation on molecules consisting of three to five atoms.
In combination with state-of-the-art multi-coincidence
techniques and elaborate theoretical modelling, this allows
tracing ultrafast hydrogen emission and obtaining
information on the result of intramolecular electron
rearrangement. Our work represents an important step towards
imaging femtosecond chemistry via Coulomb explosion.},
