## Abstract ^13^C NMR Substituent chemical shift (SCS) increments have been determined for the carbonyl carbon of a variety of substituted benzaldehydes and acetophenones. The ^13^C NMR chemical shift of the carbonyl carbon can be predicted for many diβ and trisubstituted benzaldehydes and acetophe
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 obtaini
## Abstract ^13^C NMR spectra of a large number of polyalkylated benzenes with branched and linear aliphatic chains have been studied. This resulted in the development of a general procedure that can be used for the calculation of the aromatic chemical shifts in any polyalkylated benzene.
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
