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…
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…
