Solution NMR DNP in high magnetic fields

A globally unique Dynamic Nuclear Polarization (DNP) spectrometer was constructed in Frankfurt, which operates at an electron Larmor frequency of 260 GHz and a proton frequency of 400 MHz. The microwave excitation of probes in liquid water is achieved by separating the E and B fields in the double-resonance setup.
