The carbon-13 chemical shifts of monosubstituted cyclohexane derivatives are compared with those of aliphatic compounds. The polar substituents exert a similar influence on the M-, Band y-carbons in both series of compounds. The 8-effect is shown to be characteristic mainly to the cyclic compounds,
## Abstract ^13^C NMR spectra of a series of substituted nortricyclene derivatives have been measured, and the ^13^C chemical shifts interpreted in terms of α, β, γ and δ‐effects. The nature of these substiuent shifts is discussed together with some analytical possibilities. The substituent shifts
Phenyllithium was labeled with 6Li and I3C at the ipso carbon atom, and the tetramer was measured by solid-state NMR. The chemical shift tensor data were obtained by a moment analysis of the spinning side bands and were compared with the results obtained by calculations with the IGLO method. Althoug
