Error compensation without a time penalty: robust spin-lock-induced crossing in solution NMR
Mohamed Sabba, Christian Bengs, Urvashi D. Heramun +1
A modification of the widely-used spin-lock-induced crossing (SLIC) procedure is proposed for the solution nuclear magnetic resonance (NMR) of strongly coupled nuclear spin systems…
Spinor Double-Quantum Excitation in the Solution NMR of Near-Equivalent Spin-1/2 Pairs
Urvashi D. Heramun, Mohamed Sabba, Dolnapa Yamano +5
A family of double-quantum excitation schemes is described for the solution nuclear magnetic resonance (NMR) of near-equivalent spin-1/2 pairs. These new methods exploit the spinor…
Robust Parahydrogen-Induced Polarization at High Concentrations
Laurynas Dagys, Martin C. Korzeczek, Anna J. Parker +7
Parahydrogen-Induced Polarization (PHIP) is a potent technique for generating target molecules with high nuclear spin polarization. The PHIP process involves a chemical reaction be…
Cross-correlation effects in the solution NMR spectra of near-equivalent spin-1/2 pairs
James W. Whipham, Gamal A. I. Moustafa, Mohamed Sabba +3
The NMR spectra of spin-1/2 pairs contains four peaks, with two inner peaks much stronger than the outer peaks in the near-equivalence regime. We have observed that the strong inne…
Symmetry-Based Singlet-Triplet Excitation in Solution Nuclear Magnetic Resonance
Mohamed Sabba, Nino Wili, Christian Bengs +2
Coupled pairs of spin-1/2 nuclei support one singlet state and three triplet states. In many circumstances the nuclear singlet order, defined as the difference between the singlet…
Hyperpolarization read-out through rapidly rotating fields in the zero- and low-field regime
Laurynas Dagys, Christian Bengs
An integral part of para-hydrogen induced polarization (PHIP) methods is the conversion of nuclear singlet order into observable magnetization. In this study polarisation transfer…
Low-Frequency Excitation of Singlet-Triplet Transitions. Application to Nuclear Hyperpolarization
Laurynas Dagys, Christian Bengs, Malcolm H. Levitt
Coupled pairs of nuclear spins-1/2 support one singlet state and three triplet states. Transitions between the singlet state and one of the triplet states may be driven by an oscil…
Spin-isomer conversion of water at room temperature, and quantum-rotor-induced nuclear polarization, in the water-endofullerene HO@C
Benno Meier, Karel Kouřil, Christian Bengs +6
Water exists in two forms, para and ortho, that have nuclear spin states with different symmetries. Here we report the conversion of fullerene-encapsulated para-water to ortho-wate…
