Automated projection spectroscopy in solid-state NMR

Given that solid-state NMR is being used for protein samples of increasing molecular weight and complexity, higher-dimensionality methods are likely to be more and more indispensable for unambiguous chemical shift assignments in the near future. In addition, solid-state NMR spectral properties are increasingly comparable with solution NMR, allowing adaptation of more sophisticated solution NMR strategies for the solid state in addition to the conventional methodology. Assessing first principles, here we demonstrate the application of automated projection spectroscopy for a micro-crystalline protein in the solid state.
