High-Resolution Overhauser Dynamic Nuclear Polarization Enhanced Proton NMR Spectroscopy at Low Magnetic Fields #DNPNMR #Bridge12

March 25, 2020 - Overhauser DNP spectroscopy at X-Band is mostly used to study hydration dynamics. However, using a hybrid magnet (permanent magnet in combination with sweep coils) with active shimming it is possible to record high-resolution NMR spectra with chemical shift resolution.

New limits of sensitivity of site-directed spin labeling electron paramagnetic resonance for membrane proteins #DNPNMR

March 23, 2020 - A nice overview how spinlabels can be used for structural biology studies. This includes pulsed EPR techniques such as PELDOR (DEER) and ODNP spectroscopy.
