? High field dynamic nuclear polarization spectrometer for liquid samples have been constructed. ? The field dependence of the Overhauser DNP efficiency has been measured for the first time up to 9.2T. ? High DNP enhancements for liquid samples have been observed at high magnetic fields. ? The enhancements have been compared with results from NMRD, MD and theoretical models. ? Coherent and relaxation effects within fast magnetic field changes have been analyzed.

We describe an apparatus for solid state nuclear magnetic resonance (NMR) with dynamic nuclear polarization (DNP) and magic-angle spinning (MAS) at 20-25 K and 9.4 Tesla. The MAS NMR probe uses helium to cool the sample space and nitrogen gas for MAS drive and bearings, as described earlier (Thurber et al., J. Magn. Reson. 2008) , but also includes a...

Hyperpolarization of nuclear spins through techniques such as Dynamic Nuclear Polarization (DNP) can greatly increase the signal to noise ratio in NMR measurements, thus eliminating the need for signal averaging. This enables the study of many dynamic processes which would otherwise not be amenable to study by NMR spectroscopy....
