Solid-State NMR Dipolar Recoupling in Presence of Large Chemical Shielding Anisotropies by Quaternion-Based Effective Hamiltonian Optimal Control
EnikŠBaligács, Nino Wili, José P. Carvalho +2
The paper introduces a quaternion-based optimal control approach to improve dipolar recoupling in magic-angle-spinning solid-state NMR when large chemical shielding anisotropies ar…
In situ Learning-Based Spin Engineering of Pulsed Dynamic Nuclear Polarization
Filip V. Jensen, José P. Carvalho, Nino Wili +6
Pulsed Dynamic Nuclear Polarization (DNP) is currently receiving substantial interest as a means to enhance the sensitivity of nuclear magnetic resonance (NMR) and magnetic resonan…
Extending numerical simulations in SIMPSON: Electron paramagnetic resonance, dynamic nuclear polarisation, propagator splitting, pulse transients, and quadrupolar cross terms
David L. Goodwin, Jose P. Carvalho, Anders B. Nielsen +4
Aimed at the simulation, design, and interpretation of advanced pulse experiments crossing the boundaries between nuclear magnetic resonance (NMR) and electron paramagnetic resonan…
Characterization of Strongly Hyperfine-split Protons by DNP
Gian-Marco Camenisch, Nino Wili, Gunnar Jeschke +1
Dynamic nuclear polarization experiments use microwave irradiation to transfer the larger electron polarization to nuclear spins of interest, and thus enhance the NMR transitions a…
Longitudinal Pulsed Dynamic Nuclear Polarization Transfer via Periodic Optimal Control
José P. Carvalho, Anders Bodholt Nielsen, David L. Goodwin +2
Taking inspiration from NMR spectroscopy, periodic irradiation schemes have recently shown remarkable performance when implemented into pulsed dynamic nuclear polarization (DNP) se…
Controlling Effective Hamiltonians: Broadband Pulsed Dynamic Nuclear Polarization by Constrained Random Walk and Non-linear Optimization
Anders B. Nielsen, Jose P. Carvalho, Nino Wili +5
We present constrained random walk (cRW) and figure of merit (FOM) based non-linear optimization procedures for systematic design and fundamental understanding of magnetic resonanc…
