NMR Spectroscopy for Metabolomics Research [PDF]

Metabolites, 2019
Over the past two decades, nuclear magnetic resonance (NMR) has emerged as one of the three principal analytical techniques used in metabolomics (the other two being gas chromatography coupled to mass spectrometry (GC-MS) and liquid chromatography ...

Hyperpolarization-enhanced NMR spectroscopy with femtomole sensitivity using quantum defects in diamond [PDF]

Phys. Rev. X 10, 021053 (2020), 2018
Nuclear magnetic resonance (NMR) spectroscopy is a widely used tool for chemical analysis and molecular structure identification. Because it typically relies on the weak magnetic fields produced by a small thermal nuclear spin polarization, NMR suffers from poor molecule-number sensitivity compared to other analytical techniques.

Nuclear Dipole Moments and Shielding Constants of Light Nuclei Measured in Magnetic Fields

Magnetochemistry, 2023
Nuclear magnetic resonance (NMR) is a branch of spectroscopy commonly used for identifying the chemical structure of various materials. One of the areas in which NMR provides accurate data is the determination of nuclear magnetic moments.

Searching for the Best Values of NMR Shielding and Spin-Spin Coupling Parameters: CH_4-nF_n Series of Molecules as the Example

Molecules, 2023
Attempts at the theoretical interpretation of NMR spectra have a very long and fascinating history. Present quantum chemical calculations of shielding and indirect spin-spin couplings permit modeling NMR spectra when small, isolated molecules are studied.

Characterization of a fold in TANGO1 evolved from SH3 domains for the export of bulky cargos

Nature Communications, 2023
Bulky cargos like procollagens, apolipoproteins, and mucins exceed the size of conventional COPII vesicles. During evolution a process emerged in metazoans, predominantly governed by the TANGO1 protein family, that organizes cargo at the exit sites of ...

Enantiotropy of Simvastatin as a Result of Weakened Interactions in the Crystal Lattice: Entropy-Driven Double Transitions and the Transient Modulated Phase as Seen by Solid-State NMR Spectroscopy

Molecules, 2022
In crystalline molecular solids, in the absence of strong intermolecular interactions, entropy-driven processes play a key role in the formation of dynamically modulated transient phases.
