## Abstract Conformational studies were performed on the bicyclo [4.2.0] octane system of a series of related tetracyclic diterpenes, using molecular mechanics and ^1^H NMR. Both methods gave compatible results, but did not permit the deduction of any quantitative relationship linking the vicinal c
