Abstract
Addition of lanthanide ions to epi-inositol and related compounds in aqueous solution causes shifts in their p.m.r. spectra which are interpreted as being due to diamagnetic, pseudocontact, and contactinteractions. The contact interactions show stereospecificity: they are greatest when the bonds connecting the protons to the cation form a planar zig-zag arrangement.Keywords
