## Abstract The fully extended peptide conformation (2.0~5~‐helix) has been investigated for the first time in the solid‐state by ^13^C cross‐polarization magic angle spinning NMR. The compounds examined are members of a terminally protected, homo‐oligopeptide series (from monomer through hexamer)
We have recorded high-resolution l3C-nmr spectra of collagen fibrils in the solid state by the cross-polarization-magic-angle-spinning (CP-MAS) method and analyzed the spectra with reference to those of collagenlike polypetides. We used two kinds of model polypeptides to obtain reference 13C chemica
