Abstract
Solvation effects of Li+, Na+, and Mg2+ on the mixed solvent dimethylformamide-water were investigated by the 1H NMR method. The dependence of the chemical shift of solvent protons on the mixed solvent composition was established for various concentrations of perchlorates. Isosolvation points were determined, and the dependences of charge transfer from solvent to cation on the chemical shift of solvent, as obtained by a quantum chemical calculation, were compared for the systems DMF-Mn+ and DMF-Mn+-H2O.
