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

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.

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

Experimental Control of Spin Diffusion in Liquid State NMR: A Comparison of Methods

Journal of Magnetic Resonance, 1999
In this paper, we use the formalism of the first directional derivative of the matrix exponential, to analyze and compare several experimental schemes designed to measure cross-relaxation rate constants between two spins, without having to calculate the effects due to spin diffusion.

Liquid state NMR studies of polymer dynamics and conformation

1993
Nuclear magnetic resonance experiments can reveal not only the chemical structures of polymers, together with their defects, but also a wealth of detail concerning their conformations and their motions. The local conformations combine to determine the bulk coiling properties of the polymer, such as the radius of gyration and hydrodynamic volume.

Cluster-state creation in liquid-state NMR

2007
The subject of this thesis is devoted to a class of multiparticle entangled states known as the cluster-states. In particular, we focused on a system of four spins and studied the entanglement properties of a four-qubit cluster-state, using a set of entanglement measures for quantifying multipartite entanglement.

Characterisation of PolydimethylSiloxane(PDMS) by liquid-state NMR spectroscopy

2021
This work analyzes how two liquid /viscose base materials (Base and Curing Agent by Ecoflex ?), after putting together and polymerization, will produce silicones. We want to show how vinyl groups are consumed and how methyl attached groups increase during this process. And how Base and Curing Agent are different.
