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 toggli…
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…
