✦ Synopsis

The conformational analysis of short polymer chains involves the use of statistical models, and their predictions must be checked against experimental information. Ytterbium-induced shifts in the "C NMR spectra of fatty acids provide a non-perturbing, straightforward method of simultaneously obtaining positional information about all the carbon atoms up to nine bonds away from the complexation point. Experimental results for saturated and unsaturated C-18 fatty acids are compared with the predictions of a restricted isomeric states (RIS) model.

The 13C NMR behaviour of ten acyclic terpene alcohols was examined in the presence of a chiral lanthanide shift reagent (CLSR). For each alcohol, we measured the lanthanide-induced shift (LIS) on the signals of the carbons and the splitting of some signals, which allowed the enantiomeric differentia
