AbstractPreliminary DFT investigations into the feasibility of using 33S solid-state NMR to study organic and biological molecules suggest that very large 33S quadrupolar coupling constants (>40 MHz) are not uncommon. We have therefore investigated the possibility of using recently developed ultra-wideline techniques to record such 33S powder patterns at a high magnetic field (21.1 T). AWURST-echo sequence was used to record the spectrum from a > 99.9% enriched sample of elemental sulfur, resulting in the largest 33S quadrupolar coupling constant yet measured by solid-state NMR (CQ = 43.3 MHz). Implications of this experiment are briefly discussed.
