Abstract 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.
