## Abstract The ^13^C n.m.r. spectra of 18 derivatives of the tricyclo[3.2.1.0^2,4^]octanes have been determined. This series includes methyl, hydroxyl and oxo substituted examples to compare the effects of these substituents on the skeletal carbon shieldings with those observed for the correspondi

The structure of the strained tricyclic hydrocarbon tricyclo [ 4.2.0.0'~~ I octane was determined by a combination of 1D and 2D NMR involving both proton and carbon signals. The stereochemistry of the molecule was determined by NOE difference spectroscopy. The assigned structure corresponds to the t

The 2-hydroxy and 2-hydroxy-3-methyl isomers of 5,8-dimethoxy-1,2,3,4-tetrahydro-1,4-ethanonapthalene have been characterized by -'C NMR with the aid of lanthanide shift reagents. A definite interaction with a syn oxygen, presumably with the lone electron pairs, and the aromatic carbon 8a has been e
