The 1 H and 13 C spectra of endo‐endo ‐tetracyclo[6.1.1 3,6 .0 2,7 ]dodec‐4‐en‐10‐ol have been interpreted using shift reagents and HETCOR experiments. Carbon chemical shifts are compared with tetracyclic analogs and bicyclic model compounds. Evidence for upfield δ and ε effects of 3–5 ppm is presented.
