## Abstract The enantiomeric purities of disubstituted β‐lactams were determined by ^1^H and ^13^C NMR spectroscopy using tris[3‐(trifluoromethylhydroxymethylene)‐d‐camphorato]europium(III), Eu(tfc)~3~, as a chiral shift reagent. Using a [Eu(tfc)~3~]/[lactam] ratio of 0.5, most of the resonances we

The 13C NMR behaviour of ten acyclic terpene alcohols was examined in the presence of a chiral lanthanide shift reagent (CLSR). For each alcohol, we measured the lanthanide-induced shift (LIS) on the signals of the carbons and the splitting of some signals, which allowed the enantiomeric differentia
