Method of sepctral analysis using nmr shift reagents |
| abstract |
The ability of nuclear magnetic resonance spectroscopy to distinguish between compounds and between parts of compounds is substantially increased by the use of certain rare earth chelate shift reagents. The preferred shift reagents are the europium III chelates of substituted or unsubstituted dicampholyl ligands, and europium III chelates of substituted or unsubstituted nopinato compounds. The reagents are particularly useful in determining the enantiomeric purity of compositions containing mixtures of enantiomers. |
