Ion desolvation as a mechanism for kinetic isotope …

Molecular dynamics simulations show that the desolvation rates of isotopes of Li+, K+, Rb+, Ca2+, Sr2+, and Ba2+ may have a relatively strong dependence on the metal ion mass. This inference is based on the observation that the exchange rate constant, k wex, for water molecules in the first hydration shell follows an inverse power-law mass dependence ( k wex ∝ m −γ), where the
