We report the first study of UV-induced photoisomerization probed via core ionization by an x-ray laser. We investigated x-ray ionization and fragmentation of the cyclohexadiene-hexatriene system at 850 eV during the ring opening. We find that the ion-fragmentation patterns evolve over a picosecond, reflecting a change in the state of excitation and the molecular geometry: the average kinetic energy per ion fragment and H+ ion count increase as the ring opens and the molecule elongates. We discuss new opportunities for molecular photophysics created by optical pump x-ray probe experiments.

We study the spectral phase of high-order harmonic emission as an observable for probingultrafast nuclear dynamics after the ionization of a molecule. Using a strong-fieldapproximation theory that includes nuclear dynamics, we relate the harmonic phase to thephase of the overlap integral of the nuclear wavefunctions of the initial neutral molecule andthe molecular ion after an attosecond probe delay. We determine experimentally the groupdelay of the high harmonic emission from D2 and H2 molecules, which allows us to verify therelation between harmonic frequency and the attosecond delay. The small difference in theharmonic phase between H2 and D2 calculated theoretically is consistent with ourexperimental results.
