abstract = {Aqueous solutions are crucial in chemistry, biology,
environmental science, and technology. The chemistry of
solutes is influenced by the surrounding solvation shell of
water molecules, which have different chemical properties
than bulk water due to their different electronic and
geometric structure. It is experimentally challenging to
selectively investigate this property-determining electronic
and geometric structure. Here, we report experimental
results on the non-local X-ray emission process
Intermolecular Radiative Decay, for the prototypical ions
Na+ and Mg2+ in water. We show that, in Intermolecular
Radiative Decay, an electron from the solvation shell fills
a core hole in the solute, and the released energy is
emitted as an X-ray photon. We interpret the underlying
mechanism using theoretical calculations, and show how
Intermolecular Radiative Decay will allow us to meet the
challenge of selectively probing the solvation shell from
within.},
