Tris(3-heptafluorobutyryl-d-camphorato)europium(Ill), Eu(hfbc) 3 was used to determine the optical purities of enantiomeric mixtures of tri-, di-and monoglycerides with various fatty acid chain lengths by proton magnetic resonance (PMR). Synthesized model enantiomers were used to assign PMR signals.
