SQUID-Detected Liquid State NMR in Microtesla Fields
The Journal of Physical Chemistry A, 2004Nuclear 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

Liquid-State NMR of Fluoropolymers
1996The article is a noncomprehensive review of the literature summarizing solution NMR studies of fluoropolymers performed between the 1960 s and 2012. An attempt has been made to describe a representative range of fluoropolymers as well as the NMR methods available to study their structures.

Practical aspects of liquid‐state NMR with inductively coupled solenoid coils
Magnetic Resonance in Chemistry, 2010AbstractSensitivity 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, 2002Summary 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 ...

Homonuclear decoupling for liquid-state NMR
The Journal of Chemical Physics, 2012We present a solution to the problem of decoupling of a homonuclear two-spin system having weak isotropic scalar coupling. We describe non-selective pulse sequences that create an effective field perpendicular to the coupling interaction over a broad range of chemical shifts, with a magnitude proportional to the chemical shifts. Effective decoupling is

Generating spin turbulence through nonlinear excitation in liquid-state NMR
Journal of Magnetic Resonance, 2009Chaotic 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-

Cryogen-free 400 MHz (9.4 T) solid state MAS NMR system with liquid state NMR potential
Solid State Nuclear Magnetic Resonance, 2023We show that the temporal magnetic field distortion generated by the Cold Head operation can be removed and high quality Solid-State Magic Angle Spinning NMR results can be obtained with a cryogen-free magnet. The compact design of the cryogen-free magnets allows for the probe to be inserted either from the bottom (as in most NMR systems) or, more ...
