Hydrophobic Interactions in Solution: A Nuclear Magnetic Resonance Approach

The self-association behaviour of relatively small hydrophobic organic components in aqueous mixtures has been investigated by the application of an NMR technique. The association A₂₂ parameter, which is essentially obtained from experimental intermolecular dipole-dipole relaxation data of ¹H nuclei and from NMR measurements of the self-diffusion coefficients of the organic solvents, has been determined. The composition dependence of the A₂₂ parameter allowed to point out the association behaviour of the organic components. Moreover, the effect of electrolytes and non electrolytes and of the temperature on the self-associating properties of the organic molecules has been studied.
