NOED, COSY and HETCOR experiments in conjunction with molecular mechanics calculations, were used to assign the 1 H and 13 C NMR spectra of the terpenoids α‐ionone and methyl O ‐methylpodocarpate and to investigate their stereochemistry. These compounds were used as models to investigate the ability of molecular mechanics and associated calculations to predict 1 H spin—lattice relaxation rates in molecules of this type.
