abstract = {The electronic and nuclear dynamics inside molecules are
essential for chemical reactions, where different pathways
typically unfold on ultrafast timescales. Extreme
ultraviolet (XUV) light pulses generated by free-electron
lasers (FELs) allow atomic-site and electronic-state
selectivity, triggering specific molecular dynamics while
providing femtosecond resolution. Yet, time-resolved
experiments are either blind to neutral fragments or limited
by the spectral bandwidth of FEL pulses. Here, we combine a
broadband XUV probe pulse from high-order harmonic
generation with an FEL pump pulse to observe dissociation
pathways leading to fragments in different quantum states.
We temporally resolve the dissociation of a specific
O$_2$$^+$ state into two competing channels by measuring the
resonances of ionic and neutral fragments. This scheme can
be applied to investigate convoluted dynamics in larger
molecules relevant to diverse science fields.},
