Quantum Chemical Calculation and Simulation of HSQC Experiments in Liquid-State NMR

open access: yesChinese Journal of Magnetic Resonance, 2021
Due to its high sensitivity and resolution, the heteronuclear single quantum correlation (HSQC) experiment is widely used for nuclear magnetic resonance (NMR)-based structural elucidation and research on solution state macromolecules. However, optimizing

Liquid Nuclear Magnetic Resonance (NMR) Spectroscopy in Transition—From Structure Elucidation to Multi-Analysis Method

open access: yesSeparations, 2023
As early as 1946, Felix Bloch and Edward Mills Purcell detected nuclear magnetic resonance signals, earning themselves the Nobel Prize in 1952. The same year saw the launch of the first commercial nuclear magnetic resonance (NMR) spectrometer. Since then,

Local Realistic Model for the Dynamics of Bulk-Ensemble NMR Information Processing [PDF]

open access: yes, 2001
We construct a local realistic hidden-variable model that describes the states and dynamics of bulk-ensemble NMR information processing up to about 12 nuclear spins.

On the feasibility of iron or chromium substitution for aluminium in the Al13-Keggin ion [PDF]

open access: yes, 1995
Al-27 NMR measurements in the liquid and the solid state supplemented with chemical analysis of the mixed salts; unambiguously reveal that neither tetrahedral nor octahedral aluminium can be substituted by either iron or chromium in Al-13-Keggin ion ...

Hydrogen-bonded liquid crystals with broad-range blue phases [PDF]

open access: yes, 2019
We report a modular supramolecular approach for the investigation of chirality induction in hydrogen-bonded liquid crystals. An exceptionally broad blue phase with a temperature range of 25 °C was found, which enabled its structural investigation by ...

NMR Study on the Mechanism of Cytochrome c Methionine Oxidation

open access: yesChinese Journal of Magnetic Resonance, 2023
Mitochondria generate reactive oxygen species (ROS) during respiration. Low levels of ROS are conducive to signal transduction, whereas excessive accumulation of ROS can lead to protein oxidative modification.

HR-MAS NMR Applications in Plant Metabolomics

open access: yesMolecules, 2021
Metabolomics is used to reduce the complexity of plants and to understand the underlying pathways of the plant phenotype. The metabolic profile of plants can be obtained by mass spectrometry or liquid-state NMR.

Magneto-optical contrast in liquid-state optically detected NMR spectroscopy [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
We use optical Faraday rotation (OFR) to probe nuclear spins in real time at high-magnetic field in a range of diamagnetic sample fluids. Comparison of OFR-detected NMR spectra reveals a correlation between the relative signal amplitude and the fluid Verdet constant, which we interpret as a manifestation of the variable detuning between the probe beam ...
