Determination of the three ion pair-correlation functions of a simple organic salt in solution

Abstract

Small angle neutron scattering spectra were obtained for solutions of triethylphenylammonium tetraphenylborate in dimethylformamide. The cation was hydrogenated and the anion either hydrogenated or deuterated. The solvent was mixtures of hydrogenated and deuterated dimethylformamide. The three ion pair-correlation functions have been inferred from the data using the hypernetted chain approximation and solvent averaged potentials.
