abstract = {We present a combined experimental and theoretical
investigation of the radiationless decay spectrum of an O 1s
double core hole in liquid water. Our experiments were
carried out using liquid-jet electron spectroscopy from
cylindrical microjets of normal and deuterated water. The
signal of the double-core-hole spectral fingerprints
(hypersatellites) of liquid water is clearly identified,
with an intensity ratio to Auger decay of singly charged O
1s of 0.0014(5). We observe a significant isotope effect
between liquid H$_2$O and D$_2$O. For theoretical modeling,
the Auger electron spectrum of the central water molecule in
a water pentamer was calculated using an
electronic-structure toolkit combined with
molecular-dynamics simulations to capture the influence of
molecular rearrangement within the ultrashort lifetime of
the double core hole. We obtained the static and dynamic
Auger spectra for H$_2$O, (H$_2$O)$_5$, D$_2$O, and
(D$_2$O)$_5$, instantaneous Auger spectra at selected times
after core-level ionization, and the symmetrized
oxygen-hydrogen distance as a function of time after double
core ionization for all four prototypical systems. We
consider this observation of liquid-water double core holes
as a new tool to study ultrafast nuclear dynamics.},
