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…
Bridging DNP and MAS NMR dipolar recoupling -- from static single crystal to spinning powders
Jose P. Carvalho, Anders Bodholt Nielsen, Eniko Baligacs +2
Spin engineering of advanced pulse sequences has had a transformative impact on the development of nuclear magnetic resonance (NMR) spectroscopy, to an extending degree also electr…
