Why Does 1H NMR Signal Intensity of Concentrated Aqueous Acids and Bases Decrease Anomalously?
Electrochemistry, 2022 The signal detection of quantitative 1H nuclear magnetic resonance (1H qNMR) for the amount of water in HCl and KOH aqueous solutions at low pH (pH −1.2) and high pH (pH 16) was discussed, and an “anomaly of decreasing 1H NMR signal intensity” was ...

NORD: NO Relaxation Delay NMR Spectroscopy [PDF]
Angewandte Chemie International Edition, 2021 AbstractThe novel concept of NORD (NO relaxation delay) NMR spectroscopy is introduced. The idea is to design concatenated experiments in a way that the magnetization used in the first relaxes toward equilibrium during the second and vice versa, thus saving instrument time.

Fitting side-chain NMR relaxation data using molecular simulations
bioRxiv, 2020 Proteins display a wealth of dynamical motions that can be probed using both experiments and simulations. We present an approach to integrate side chain NMR relaxation measurements with molecular dynamics simulations to study the structure and dynamics ...

Exploring catalyst passivation with NMR relaxation [PDF]
Faraday Discussions, 2017 NMR relaxation has recently emerged as a novel and non-invasive tool for probing the surface dynamics of adsorbate molecules within liquid-saturated mesoporous catalysts. The elucidation of such dynamics is of particular relevance to the study and development of solvated green catalytic processes, such as the production of chemicals and fuels from bio ...
