In conclusion, NMR relaxometry, through its ability to probe dynamic processes over a wide range of timescales and magnetic fields, remains a powerful tool in the study of biological macromolecules. Its applications in both solution and solid-state systems, as well as in paramagnetic and diamagnetic contexts, continue to provide valuable insights into the molecular mechanisms underlying biological function. Future developments in this field will undoubtedly expand its utility and impact, driving forward our understanding of molecular dynamics in increasingly complex biological environments.
