Abstract 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.
