Recent Advances in High-Resolution Solid-State NMR Spectroscopy

Diverse complex systems may be studied by the new methods in solid-state NMR spectroscopy described herein. These methods use magic-angle spinning (MAS) on samples in oriented bilayers (right picture) and in orientationally disordered samples (left picture). Systems as diverse as uniformly 13C,15N-labeled proteins, model membrane systems, and silk, as produced by the silkworm, can be structurally characterized.
