Ultrahigh‐Resolution NMR Spectroscopy [PDF]
Angewandte Chemie International Edition, 2014 All psyched up: A flexible and general pure shift experiment (PSYCHE) has been developed that offers superior sensitivity, spectral purity, and tolerance of strong coupling over existing methods for broadband homonuclear decoupling. The partial spectra of estradiol in [D6]DMSO obtained by normal 1H NMR spectroscopy and PSYCHE are shown for comparison.

Shifts in the selectivity filter dynamics cause modal gating in K+ channels
Nature Communications, 2019 Spontaneous activity shifts at constant experimental conditions are widespread among ion channels but the molecular origins are poorly understood. Here, using solid-state NMR and MD simulations, the authors reveal that modal gating shifts in K + channels

Correlation of high-field and zero- to ultralow-field NMR properties using 2D spectroscopy [PDF]
, 2020 The field of zero- to ultralow-field (ZULF) nuclear magnetic resonance (NMR) is currently experiencing a rapid growth, owing to the progress in optical magnetometry, and also attractive features of ZULF NMR, such as low hardware cost and excellent spectral resolution achieved under ZULF conditions. In this work, an approach is proposed and demonstrated

Demonstration of NV-detected $^{13}$C NMR at 4.2 T [PDF]
, 2023 The nitrogen-vacancy (NV) center in diamond has enabled studies of nanoscale nuclear magnetic resonance (NMR) and electron paramagnetic resonance with high sensitivity in small sample volumes. Most NV-detected NMR (NV-NMR) experiments are performed at low magnetic fields.

Mode of action of teixobactins in cellular membranes
Nature Communications, 2020 The natural antibiotic teixobactin kills bacteria by direct binding to their cognate cell wall precursors (Lipid II and III). Here authors use solid-state NMR to reveal the native binding mode of teixobactins and show that teixobactins only weakly bind ...

Nuclear Magnetic Resonance (NMR) Spectroscopy in Food Science: A Comprehensive Review.
Comprehensive Reviews in Food Science and Food Safety, 2018 Nuclear magnetic resonance (NMR) spectroscopy is a robust method, which can rapidly analyze mixtures at the molecular level without requiring separation and/or purification steps, making it ideal for applications in food science.

High-pressure NMR spectroscopy in studies of the conformational composition of small molecules of ibuprofen in supercritical carbon dioxide [PDF]
, 2020 An experimental approach in conducting NMR measurements at supercritical parameters of state is discussed. A novel design of the high-pressure NMR cell was developed which allowed eliminating the field inhomogeneity and, thus, increasing the sensitivity of the experiment at the supercritical state.

NMRFAM-SPARKY: enhanced software for biomolecular NMR spectroscopy
Bioinform., 2014 Summary: SPARKY (Goddard and Kneller, SPARKY 3) remains the most popular software program for NMR data analysis, despite the fact that development of the package by its originators ceased in 2001.

Room temperature chiral discrimination in paramagnetic NMR spectroscopy [PDF]
Phys. Rev. Lett. 116, 163001 (2016), 2016 A recently proposed theory of chiral discrimination in NMR spectroscopy based on the detection of a molecular electric polarization $\mathbf{P}$ rotating in a plane perpendicular to the NMR magnetic field [A. D. Buckingham, J. Chem. Phys. $\mathbf{140}$, 011103 (2014)], is here generalized to paramagnetic systems.
