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.

Intramolecular Hydrogen Bonding Involving Organic Fluorine: NMR Investigations Corroborated by DFT-Based Theoretical Calculations

Molecules, 2017
The combined utility of many one and two dimensional NMR methodologies and DFT-based theoretical calculations have been exploited to detect the intramolecular hydrogen bond (HB) in number of different organic fluorine-containing derivatives of molecules,

Multilayer protein corona on gold nanorod surface: First evidence of soft corona protein-protein interactions using solution NMR spectroscopy

Applied Surface Science Advances, 2022
The nanoparticle surfaces interact readily with biomolecules, including proteins forming a corona. The protein layer that directly interacts with the nanoparticle surface is usually explored. Non-covalent interactions of proteins in the second layer have

O- vs. N-protonation of 1-dimethylaminonaphthalene-8-ketones: formation of a peri N–C bond or a hydrogen bond to the pi-electron density of a carbonyl group [PDF]

, 2014
X-ray crystallography and solid-state NMR measurements show that protonation of a series of 1-dimethylaminonaphthalene-8-ketones leads either to O protonation with formation of a long N–C bond (1.637–1.669 Å) between peri groups, or to N protonation and ...

Blind spheres of paramagnetic dopants in solid state NMR [PDF]

, 2019
Solid-state NMR on paramagnetically doped crystal structures gives information about the spatial distribution of dopants in the host. Paramagnetic dopants may render NMR active nuclei virtually invisible by relaxation, paramagnetic broadening or ...

Supramolecular Synthon Identification in Azelaic Acid – Isonicotinamide

Journal of Magnetic Resonance Open, 2022
Supramolecular synthons are the smallest structural units that contain the information inherent in building large molecular assemblies. Here, we apply solid-state NMR methods for the identification of the synthon in a cocrystal of Azelaic acid [(CH2)7 ...

Solid-state NMR Investigation of the Host-guest Interactions in Gas Adsorption and Chemical Separation Using MOFs as Adsorbents

Chinese Journal of Magnetic Resonance, 2023
Due to its sensitivity to the local geometries and chemical environments, solid-state nuclear magnetic resonance (NMR) is widely applied to investigate the host-guest interactions between metal-organic frameworks (MOFs) and guest molecules in the studies
