Application of the competitive preferential solvation theory to ion–molecule interactions

Abstract

The n.m.r. spectroscopic behaviour of first group monovalent ions, ⁷Li⁺, ²³Na⁺, ⁸⁷Rb⁺, ¹³³Cs⁺ and of ¹⁹F^– has been re-examined in the light of the competitive preferential solvation theory. It appears that this theory can successfully account for the relatively strong ion–molecule interactions in the whole concentration range. It is shown that classical treatment will yield the same results provided it considers the solvent explicitly.
