Natural abundance solid-state S-33 NMR study of NbS3: applications for battery conversion electrodes

• We report ultra-wideline, high-field natural abundance solid-state S-33 NMR spectra of the Li-ion battery conversion electrode NbS3, the first S-33 NMR study of a compound containing disulfide (S-2(2-)) units. The large quadrupolar coupling parameters (C-Q approximate to 31 MHz) are consistent with values obtained from DFT calculations, and the spectra provide evidence for the linear Peierls distortion that doubles the number of S-33 sites.
