13C NMR spectra of the three title polymers have been determined for polymers of different tacticities. Assignments to the various possible HWHT/TT and m/r dyad structures were made. These were facilitated by the use of optically active monomers in the case of 1 and 3. In the precursor polymers the
## Abstract A detailed analysis of the ^1^H and ^13^C NMR spectra of C‐2 aryl and alkyl/desalkyl substituted isomeric __exo__‐ and __endo__‐5‐methylbicyclo[3.2.1]octane‐6,8‐diones is presented. The chemical shift of the C‐5 angular methyl, the C‐2 alkyl/olefinic (C‐10)/C‐2 methine protons, the arom
