Do water's electrons care about electrolytes?

ABSTRACT: Ions have a profound effect on the geometrical structure of liquid water and an aqueous environment is known to change the electronic structure of ions. Here we combine photoelectron spectroscopy measurements from liquid microjets with molecular dynamical and quantum chemical calculations to address the reverse question, to what extent do ions affect the electronic structure of liquid water? We study aqueous solutions of sodium iodide (NaI) over a wide concentration range, from nearly pure water to 8 M solutions, recording spectra in the 5 to 60 eV binding energy range to include all water valence and the solute Na⁺ 2p, I^- 4d, and I^- 5p orbital ionization peaks. We observe that the electron binding energies of the solute ions change only slightly as a funct
