Abstract: ~(13)C NMR spectral studies have been performed on the structure of the adducts of lanthanide ions and L-lysine using aqueous lanthanide shift reagents. The lanthanide-induced shifts are separated into contact and dipolar components by a new method of separation with a self-consistent manner. The geometry of L-lysine is described by the geometric factors derived from dipolar shifts, optimized by computer search, and checked by Euler transformation.

Key words: L-lysine, Structure, Lanthanide shift reagent, 13C-NMR
