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…
Cyclicity of interaction frame transformations
Michael C D Tayler, Mohamed Sabba
We identify a cyclic property of rotation sequences involving piecewise displacements about arbitrary axes in three dimensions. Specifically, when transformation to the togglin…
A quantum Pascal pyramid and an extended de Moivre-Laplace theorem
Mohamed Sabba
Pascal's triangle is widely used as a pedagogical tool to explain the "first-order" multiplet patterns that arise in the spectra of coupled spin-1/2 systems in magnetic res…
The Rh NMR Spectroscopy and Relaxometry of the Rhodium Formate Paddlewheel Complex
Harry Harbor Collins, Mohamed Sabba, Gamal Moustafa +4
The NMR spectroscopy of spin-1/2 nuclei with low gyromagnetic ratio is challenging, due to the low NMR signal strength. Methodology for the rapid acquisition of Rh NMR para…
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…
