Upscaling the hyperpolarization sample volume of an automated hydrogenative parahydrogen-induced polarizer
Yenal Gökpek, Jan-Bernd Hövener, Andrey N. Pravdivtsev
Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) suffer from inherently low sensitivity due to the weak thermal polarization of nuclear spins. Parahydrogen-ind…
Compact magnetic field cycling system with the range from nT to 9.4 T exemplified with 13C relaxation dispersion and SABRE-SHEATH hyperpolarization
Josh P. Peters, Charbel D. Assaf, Jan-Bernd Hövener +1
We present a compact magnetic field cycling system for high-resolution NMR spectrometers. The system enables the transfer of the sample from B0 field of 9.4 T to about nT and all f…
Maximizing NMR Sensitivity: A Guide to Receiver Gain Adjustment
Josh P. Peters, Frank D. Sönnichsen, Jan-Bernd Hövener +1
Novel methods and technology drive the rapid advances of nuclear magnetic resonance (NMR). The primary objective of developing novel hardware is to improve sensitivity and reliabil…
LIGHT-SABRE hyperpolarizes 1-^{13}C-pyruvate continuously, without magnetic field cycling
Andrey N. Pravdivtsev, Kai Buckenmaier, Nicolas Kempf +7
Nuclear spin hyperpolarization enables real-time observation of metabolism and intermolecular interactions in vivo. 1-13C-Pyruvate is the leading hyperpolarized tracer currently un…
Symmetry constraints on spin order transfer in parahydrogen-induced polarization (PHIP)
Andrey N. Pravdivtsev, Danila A. Barskiy, Jan-Bernd Hövener +1
It is well known that the association of parahydrogen (pH2) with an unsaturated molecule or a transient metalorganic complex can enhance the intensity of NMR signals; the effect is…
Selectively pulsed spin order transfer increases parahydrogen-induced NMR amplification of insensitive nuclei and makes polarization transfer more robust
Andreas B. Schmidt, Arne Brahms, Frowin Ellermann +6
We describe a new method for pulsed spin order transfer (SOT) of parahydrogen induced polarization (PHIP) that enables close to 100 % polarization in incompletely 2H-labeled molecu…
Coherent evolution of signal amplification by reversible exchange in two alternating fields (alt-SABRE)
Andrey N. Pravdivtsev, Nicolas Kempf, Markus Plaumann +4
Parahydrogen (pH2) is a convenient and cost efficient source for magnetic resonance signal enhancement. Transient interaction of pH2 with a metal organic complex in a signal amplif…
Continuous Radio Amplification by Stimulated Emission using Parahydrogen Induced Polarization (PHIP-RASER) at 14 Tesla
Andrey N. Pravdivtsev, Frank D. Sönnichsen, Jan-Bernd Hövener
Nuclear Magnetic Resonance (NMR) is an intriguing quantum-mechanical effect that is used for daily life medical diagnostics and chemical analysis alike. Numerous advancements have…
Simultaneous observation of high order multiple quantum coherences at ultralow magnetic fields
K. Buckenmaier, K. Scheffler, M. Plaumann +8
We present a method for the simultaneous observation of heteronuclear multi-quantum coherences (up to the 3rd order), which give an additional degree of freedom for ultralow magnet…
