Nuclear Magnetic Resonance (NMR) spectroscopy suffers from low sensitivity due to the low nuclear spin polarization obtained within practically achievable external magnetic fields. Dynamic Nuclear Polarization (DNP) refers to the techniques that increases NMR signal intensity by transferring spin polarization from electrons to the nuclei.

High-Resolution Overhauser Dynamic Nuclear Polarization Enhanced Proton NMR Spectroscopy at Low Magnetic Fields #DNPNMR #Bridge12
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. This is an example of the research and development activities performed at Bridge12.
