13C NMR spectra of 36 endo-endo, exo-endo and exo-exo tetracyclic fused norbornyl compounds are interpreted.Stereochemical influences on 1H and 13C chemical shifts are compared and discussed.Only upfield δ and ε effects are observed. KEY WORDS: Upfield δ and ε effects, 13C chemical shifts, Tetracyclododecane derivatives
