Abstract

NaSO₄⁻(H₂O)_n (n = 0–4) clusters have been generated in the gas phase as model systems to simulate the first dissolution steps of sulfate salts in water; photoelectron spectroscopy and theoretical calculations indicate that the first three water molecules strongly interact with both Na⁺ and SO₄²⁻, forming a three-water solvation ring to start to pry apart the Na⁺SO₄²⁻ contact ion pair.
