Solid-state NMR spectroscopy [PDF]

Nature Reviews Methods Primers, 2021
Solid-state nuclear magnetic resonance (NMR) spectroscopy is an atomic-level method used to determine the chemical structure, three-dimensional structure, and dynamics of solids and semi-solids. This Primer summarizes the basic principles of NMR as applied to the wide range of solid systems.

Solid State NMR Characterization of Complex Metal Hydrides systems for Hydrogen Storage Applications [PDF]

Journal of Analytical Science and Technology, 2011
Solid state NMR is widely applied in studies of solid state chemistries for hydrogen storage reactions. Use of 11B MAS NMR in studies of metal borohydrides (BH4) is mainly focused, revisiting the issue of dodecaborane formation and observation of 11B{1H}

The molecular pH-response mechanism of the plant light-stress sensor PsbS

Nature Communications, 2021
Photosystem II subunit S (PsbS) senses thylakoid lumen acidification when plants are exposed to excess light. Here the authors use NMR and IR spectroscopy to show that low pH causes repositioning of an amphipathic helix and folding of a loop involving ...

Applications of Solid-State Nuclear Magnetic Resonance Spectroscopy in Methanol-to-Olefins Reaction

Chinese Journal of Magnetic Resonance, 2021
Methanol-to-olefins (MTO) is a prevalent industrial process for producing light olefins from the non-petroleum route. Molecular sieves are core catalysts for MTO owing to their unique pore structure and tunable acidity.
