Starting from pure DMSO (DMSO‐d 6 ) the solvent‐solvent interactions detectable in the aqueous systems were investigated by means of v SO and v CS . On the basis of the results obtained the solvation behaviour of cations (Li + , Mg 2+ , Al 3+ ) in DMSO (DMSO‐d 6 )H 2 O mixtures is discussed. In spite of the prevailing solvent‐solvent interactions direct cation‐DMSO (DMSO‐d 6 ) interactions can still be proved in solutions rich in water, which suggest preferred cation solvation by the organic molecule.
