## Abstract ^13^C n.m.r. studies of a series of tricarbocyclic ring C aromatic diterpenoids using proton‐noise and single‐frequency off‐resonance decoupling, partially relaxed Fourier transform techniques, shift reagents and specifically labelled derivatives have permitted unequivocal assignments o
## Abstract ^13^C NMR spectra of friedelan, friedelan‐21‐one, friedelan‐6‐one, friedelane‐321‐dione, friedelane‐3,6‐dione and friedelane‐3,6,21‐trione have been recorded and signals assigned using off‐resonance decoupling, inversion recovery and lanthanide induced shift techniques.
## Abstract The NMR spectra of eight alkyl vinyl sulphides have been analyzed and the parameters compared with those obtained from an analogous series of oxygen derivatives. It is shown that a definite parallelism exists between chemical shifts and HH coupling. Difference in absolute values have b
