Molecular complexes. Part 15.—H Nuclear magnetic resonance T1 studies of solvation and complexation in the C6H6+ CDCl3+ C6H12 system

Abstract

¹ H n.m.r. studies of the interaction between chloroform-d and benzene in the presence of cyclohexane provide T₁ data which are used to elucidate the mechanism of the interaction. It is proposed that benzene is preferentially attracted to [²H₁]chloroform “solvation shells” in which short lived bimolecular complexes are formed. The data are interpreted on this basis to show that the shell contains ≈ 12 molecules of benzene.
