Solid state nuclear magnetic resonance of polymers

open access: yesJournal of Magnetic Resonance Open, 2023
The development of Solid-State Nuclear Magnetic Resonance (SSNMR) in Argentina took a great buster at the beginning of the 1990s along with the acquisition of many “state-of-the-art” high-field NMR spectrometers, two of them multipurpose solid-liquid ...

Spin Liquid State in an Organic Mott Insulator with Triangular Lattice [PDF]

open access: yes, 2003
$^{1}$H NMR and static susceptibility measurements have been performed in an organic Mott insulator with nearly isotropic triangular lattice, $\kappa$-(BEDT-TTF)$_{2}$Cu$_{2}$(CN)$_{3}$, which is a model system of frustrated quantum spins.

NMR-Based Chromatography Readouts: Indispensable Tools to “Translate” Analytical Features into Molecular Structures

open access: yesCells, 2022
Gaining structural information is a must to allow the unequivocal structural characterization of analytes from natural sources. In liquid state, NMR spectroscopy is almost the only possible alternative to HPLC-MS and hyphenating the effluent of an ...

Randomized benchmarking of single- and multi-qubit control in liquid-state NMR quantum information processing [PDF]

open access: yes, 2008
Being able to quantify the level of coherent control in a proposed device implementing a quantum information processor (QIP) is an important task for both comparing different devices and assessing a device's prospects with regards to achieving fault ...

On the Tautomerism of N-Substituted Pyrazolones: 1,2-Dihydro-3H-pyrazol-3-ones versus 1H-Pyrazol-3-ols

open access: yesMolecules, 2018
The tautomerism of 1-phenyl-1,2-dihydro-3H-pyrazol-3-One was investigated. An X-ray crystal structure analysis exhibits dimers of 1-phenyl-1H-pyrazol-3-ol units.

Large‐scale NMR simulations in liquid state: A tutorial [PDF]

open access: yesMagnetic Resonance in Chemistry, 2017
Liquid state nuclear magnetic resonance is the only class of magnetic resonance experiments for which the simulation problem is solved comprehensively for spin systems of any size. This paper contains a practical walkthrough for one of the many available simulation packages — Spinach.

Sample convection in liquid-state NMR: why it is always with us, and what we can do about it.

open access: yesJournal of magnetic resonance (San Diego, Calif. 1997 : Print), 2015
Many NMR experiments on liquids suffer if the sample convects. This is particularly true for applications, such as the measurement of diffusion, that rely on spatial labelling of spins.

The Application of in Operando Liquid State NMR on Macromolecular Material Characterization

open access: yesChinese Journal of Magnetic Resonance, 2019
With the shift toward the study of systems in operando and with increasing sensitivity, in operando nuclear magnetic resonance (NMR) is becoming more and more widely used in the field of polymer materials. In operando liquid state NMR provide mechanistic

Assessment of geographical origin and production period of royal jelly by NMR metabolomics

open access: yesChemical and Biological Technologies in Agriculture, 2020
Background Royal jelly (RJ) represents the most valuable product of beekeeping activities. The illegal introduction of RJ of uncertain quality/origin in European agrofood markets is not controlled, since the conventional analytical methods cannot ...

Geometric quantum gates in liquid-state NMR based on a cancellation of dynamical phases [PDF]

open access: yes, 2009
A proposal for applying non-adiabatic geometric phases to quantum computing, called the double-loop method [S.-L. Zhu and Z. D. Wang, Phys. Rev. A {\bf 67}, 022319 (2003)], is demonstrated in a liquid state NMR quantum computer.
