## Abstract The use of lanthanide shift reagents (LSR's) to obtain additional structural information from nuclear magnetic resonance studies has gained widespread acceptance. However, there has not been general agreement with regard to the most appropriate methodology for analysis of the shifted NM

Lanthanide shift reagents have been used for the conformational analysis of bicyclo[3.3.1]nonan-g-one. Comparison of predicted shifts and experimental values obtained with Eu(fod)3 indicate that the boat-chair conformation constitutes 22% of the mixture of conformers. Bicyclo[3.3.l]nonane (1) and it

## Abstract The NMR spectra of acetone, adamantanone and 1‐adamantanecarbonitrile have been studied in the presence of Eu(fod)~3~ in various solvents. A substantial solvent dependence is found for the association constants between shift reagent and substrate. The magnitude of the association consta
