Solute-solvent interactions. VII. Proton magnetic resonance and infrared study of ion solvation in dipolar aprotic solvents

  • J. F. Coetzee
  • W. R. Sharpe


The solvation of a variety of ions by the dipolar aprotic solvents acetonitrile, sulfolane, and dimethylsulfoxide was studied through the influence of salts on the proton magnetic resonance chemical shifts of the solvents. In the case of acetonitrile the results were supplemented with infrared measurements, which showed that in general anions affect only the C−H and cations both the C−C and particularly the C≡N stretching frequencies of acetonitrile. The results are discussed in conjunction with transport and other data already in the literature. Current views on the structure of these solvents are summarized.
