## Abstract The ^13^C and ^1^H spectra of a series of aromatic ketones, ethers and ketoโethers were studied using the lanthanide shift reagent (LSR) Yb(fod)~3~ and the data analyzed using the lanthanide induced shift (LIS) ratio method. Studies were carried out on phenalenone, 6โmethoxyphenalenone,
An assignment of relative configurations has been achieved for the diastereomeric racernates(lR2R,lS2S) and (1R2S, 1S2R) of 3,3-dimethyl-l,2-diphenylbuta~-l-ol through the comparative analysis of the respective chemical shifts induced by Eu(fod), in the 'H and '"C NMR spectra, and the corresponding
Binuclear lanthanide(III)-silver(I) f3-diketonate chelates are effective N M R shift and relaxation reagents for substrates containing one or two multiply bonded nitrogen atoms, despite the fact that some of the substrates are able to react with lanthanide chelates alone. The silver cation is bonded
