abstract = {In this work, we use an extreme-ultraviolet (XUV)
free-electron laser (FEL) to resonantly excite the
I: 4$d_{5/2}–σ^∗$ transition of a gas-phase
di-iodomethane (CH$_2$I$_2$) target. This site-specific
excitation generates a 4$d$ core hole located at an iodine
site, which leaves the molecule in a well-defined excited
state. We subsequently measure the time-dependent absorption
change of the molecule with the FEL probe spectrum centered
on the same I: 4$_d$ resonance. Using ab initio
calculations of absorption spectra of a transient
isomerization pathway observed in earlier studies, our
time-resolved measurements allow us to assign the timescales
of the previously reported direct and indirect dissociation
pathways. The presented method is thus sensitive to
excited-state molecular geometries in a time-resolved
manner, following a core-resonant site-specific trigger.},
