Field-dependent relaxation profiles of biomolecular systems.

The function of biomolecular systems, including biological macromolecules, often crucially depends on their dynamics. Nuclear magnetic resonance (NMR) is one of the most informative methods used to study biomolecules and their internal mobility, with atomic resolution, in near-physiological conditions. NMR relaxation profiles, obtained from the field dependence of the nuclear relaxation rates, in particular, offer the possibility to probe dynamic processes over a wide range of time scales.
