Distribution of small organic cations in aqueous solutions

Zusammenfassung

Small-angle neutron scattering experiments were performed on solutions of n-tetrabutylammonium bromide in heavy water. The hypernetted chain integral equation with solvent-averaged pair potentials was used to describe the scattering spectra. It is shown that previous model potentials, based only on thermodynamic measurements, do not correctly reproduce the scattering spectra.
