## Abstract We use the nmr data concerning the C^α^HC^β^H fragment in eight peptides with rigid side chains to parametrize a Karplus correlation between the vicinal proton __J__~αβ~ coupling constant and the dihedral angle θ. When considering molecules containing the fragment C^α^H^α^C^β^H^β^H^β′

## Abstract Solid‐state NMR spectroscopy was applied to the analysis of melanins prepared by peroxidase‐H~2~O~2~ oxidation of dopamines specifically ^13^C labelled in the α‐ or β‐side chain positions. A surprisingly diverse pattern of signals indicated the presence of uncyclized dopamine and noradr

X-ray crystallographic analyses are reported for the two title compounds (8 and 9), of which the former crystallized in two modifications (8n and 8b). In all three structures, the pyranose rings have the %, (D) conformation and the substituents at C-l are axial and those at C-24-4 are equatorial. Th
