## Abstract An NMR method is described for assaying the enantiomer composition of the pharmacologically active material penicillamine (**1**), using tris‐(3‐heptafluorobutyryl‐__d__‐camphorato)europium. The L enantiomer can be detected at levels of 0Β·4 to 0Β·5% in DL mixtures. Problems due to the in

The complete assignment of the proton NMR spectra of several a-, pand ynaphthoflavones at 100 MHz using Eu(fod), and double resonance experiments has been carried out. The compounds were found to associate at the carbonyi oxygen, by analogy with flavones where complete structural assignment can be a
