Dipolar relaxation of multiple-quantum NMR coherences in a linear homogeneous chain of 19F nuclei in calcium fluoroapatite [PDF]

open access: yesMagnetic Resonance in Solids, 2016
Experimental and theoretical investigations of dynamics and relaxation of multiple quantum (MQ) nuclear magnetic resonance (NMR) coherences of the zeroth and second orders are performed in a quasi-one-dimensional chain of nuclear spins of 19F in calcium ...

High-resolution NMR studies of structure and dynamics of human ERp27 indicate extensive interdomain flexibility [PDF]

open access: yes, 2013
ERp27 (endoplasmic reticulum protein 27.7 kDa) is a homologue of PDI (protein disulfide-isomerase) localized to the endoplasmic reticulum. ERp27 is predicted to consist of two thioredoxin-fold domains homologous with the non-catalytic b and b' domains of

Ultrafast transverse relaxation exchange NMR spectroscopy [PDF]

open access: yes, 2022
Molecular exchange between different physical or chemical environments occurs due to either diffusion or chemical transformation. Nuclear magnetic resonance (NMR) spectroscopy provides a means of understanding the molecular exchange in a noninvasive way ...

A High-precision Processing Method of Two-dimensional NMR Logging Data Based on Component Compensation

open access: yesChinese Journal of Magnetic Resonance, 2022
Two-dimensional nuclear magnetic resonance (NMR) technology can perform non-destructive, rapid and quantitative measurement and characterization of various hydrogen-containing fluids in the reservoir, but is limited by the acquisition methods and ...

NMR as a Probe of the Relaxation of the Magnetization in Magnetic Molecules [PDF]

open access: yesPhysical Review Letters, 2005
We investigate the time autocorrelation of the molecular magnetization $M(t)$ for three classes of magnetic molecules (antiferromagnetic rings, grids and nanomagnets), in contact with the phonon heat bath. For all three classes, we find that the exponential decay of the fluctuations of $M(t)$, associated with the irreversible exchange of energy with ...
