SQUID-Detected Liquid State NMR in Microtesla Fields

The Journal of Physical Chemistry A, 2004
Nuclear magnetic resonance (NMR) experiments performed in magnetic fields on the order of microtesla yield line widths comparable to the lifetime limit even in grossly inhomogeneous magnets. The potential loss in sensitivity is overcome by combining prepolarization in fields on the order of millitesla and signal detection with a Superconducting Quantum

Insights into the Structure of Sucralfate by Advanced Solid- and Liquid-State NMR

Molecular Pharmaceutics
Sucralfate, which is a sucrose octasulfate aluminum complex, is an active pharmaceutical ingredient (API) falling in the category of cytoprotective agents which are very effective for gastric and duodenal ulcers. On interaction with stomach acid, it ionizes into aluminum and sucrose octasulfate ions to form a protective layer over the ulcerated region ...

SPINEVOLUTION: A powerful tool for the simulation of solid and liquid state NMR experiments

Journal of Magnetic Resonance, 2006
Exact numerical simulations of NMR experiments are often required for the development of new techniques and for the extraction of structural and dynamic information from the spectra. Simulations of solid-state magic angle spinning (MAS) experiments can be particularly demanding both computationally and in terms of the programming required to carry them

Practical aspects of liquid‐state NMR with inductively coupled solenoid coils

Magnetic Resonance in Chemistry, 2010
AbstractSensitivity enhancement by the use of inductively coupled milli‐ and microcoils has been demonstrated in solid‐state as well as liquid‐state NMR. In this work, we discuss the practical aspects of using inductively coupled solenoid coils of different sizes in a liquid‐state NMR spectrometer. The sensitivity and resolution enhancements from these

Generating spin turbulence through nonlinear excitation in liquid-state NMR

Journal of Magnetic Resonance, 2009
Chaotic dynamics of a water magnetization in a 600 MHz NMR spectrometer was generated by a radiation damping-based electronic feedback. Erratic induction signal was observed for several tens of seconds. The analysis of the data shows that this chaotic behaviour can be ascribed to spin turbulence in the sample and that a simpler model based on the three-

Structure of Thermally Modified Wood Studied by Liquid State NMR Measurements

Holzforschung, 2002
Summary Thermal modification is a technique to produce wood with increased dimensional stability and lower equilibrium moisture content. 2H NMR relaxation measurements and pulsed field gradient (PFG-NMR) methods are non-invasive spectroscopic techniques that can be used to measure the response of liquid confined in porous materials and ...

The Flexibility of SIMPSON and SIMMOL for Numerical Simulations in Solid-and Liquid-State NMR Spectroscopy

Monatshefte f?r Chemie / Chemical Monthly, 2002
Addressing the need for numerical simulations in the design and interpretation of advanced solid- and liquid-state NMR experiments, we present a number of novel features for numerical simulations based on the SIMPSON and SIMMOL open source software packages.

Ensemble Quantum Computing by Liquid-State NMR Spectroscopy

2001
Abstract : We propose to use NMR as a testbed to develop general methods for solving computational problems on EQC's, to study the fundamental physics and computer science of these machines, and to learn how to make optimal use of the trade-offs that their unique capabilities permit us to make.

Non-Bloch decay of Rabi oscillations in liquid state NMR

EPL (Europhysics Letters), 2018
Rabi oscillations are known to exhibit non-Bloch behaviour in anisotropic media. In this letter, we report an experimental observation of non-Bloch decay of Rabi oscillations in isotropic liquid state NMR. To avoid the dephasing due to the radio-frequency inhomogeneities, we develop a modified version of the rotary echo protocol and use it to determine
