Abstract: | A model is proposed in which the NMR relaxation dispersion profiles of biomolecule water solutions are interpreted in terms of magnetic field fluctuations due to the backbone vibrations involving the biopolymer paramagnetic nuclei. This model, which takes into account the experimental evidence which has appeared in the literature for a “fractal-like” density of vibrational state for the protein backbone, has been used to fit some experimental NMR relaxation profiles of biomolecule water solutions. The results obtained are discussed critically in connection with the data reported in the related literature. |
