## Abstract ^13^C NMR spectra of 27‐hydroxyfriedelane, kokoonol (27‐hydroxyfriedelan‐3‐one) and kokoononol (27‐hydroxyfriedelan‐3,21‐dione) have been recorded and signals assigned using the off‐resonance decoupling, inversion recovery and lanthanide induced shift techniques.

✦ Synopsis
Abstract
The high temperature ^13^C NMR spectra of the methyl esters of deuteroporphyrin‐IX and protoporphyrin‐IX, and octaethylporphyrin show sharp discrete signals for the inner macrocycle carbon resonances. The temperature dependence of these shifts is discussed.
