Model of the orientation symmetry of water molecules in biopolymers (by NMR Spectra)

Spectra of proton and deuteron magnetic resonance of water molecules in oriented biopolymer samples (collagen, DNA, cellulose) are interpreted on the basis of a model of molecular Schottki‐type diffusion. The presence of narrow splittings are shown to be the result of slight distortions of “ideal” symmetry of orientations of p ‐ p and O ‐ D vectors, corresponding to the point symmetry group of a tetrahedron, one of whose C 3 ‐axes is oriented along the fiber axis.
