Solid-state nuclear magnetic resonance (NMR) spectroscopy is widely used to investigate the structure and dynamics of a broad range of materials.
In the case of paramagnetic materials, interactions with unpaired electrons lead to markedly broadened NMR frequency ranges, increased linewidths, and shortened longitudinal relaxation times (T1). These features necessitate experimental approaches and spectral interpretation strategies that differ from those used for diamagnetic systems. In this paper, we summarize key spectroscopic characteristics of paramagnetic materials in solid-state NMR and present several representative examples illustrating these phenomena.
