Nuclear Magnetic Resonance (NMR) provides unique information on the local structure and dynamics of condensed matter and serves as a versatile technique in physics and material science, as well as a valuable tool in chemistry, biochemistry, molecular biology, and medicine. Solid-state NMR spectroscopy allows investigation of a wide range of materials, including crystalline and disordered solids, with unique capabilities for probing both structural and magnetic properties. Local crystal symmetry, valence state. In magnetic solids, though often challenging, NMR spectroscopy yields additional information about the magnetic state of atoms, can study individual magnetic sublattices, or reveal the direction of magnetic moments.

In the talk, the basic principle of NMR and related spectroscopy will be introduced, its application to solids and magnetic solids will be covered – with a focus on areas where NMR spectroscopy can serve as a complementary method to diffraction techniques.
