High-resolution vibrational spectra of oriented D2O-exchanged collagen fibres at 20 and 110 K have been measured using the pulsed-neutron spectrometer TFXA at ISIS. Numerous bands between 20 and 3800 cm-1 show a level of fine structure approaching that of optical spectra. The principal features of the spectra observed are discussed in the context of recent work on collagen and related triple-helical polypeptides, and some tentative assignments are made.
