Solid-state NMR in biogeochemistry

Since the development of cross-polarization (CP) and magic angle spinning (MAS) and the subsequent rise of solid-state NMR, the technique has found its way into soil science and is now a well-established characterization method for soil organic matter. It can be used for a large variety of non-destructive applications e.g. relaxation measurements, structure resolution or identification of binding-induced peak shifts.
