? High field Dynamic Nuclear Polarization spectrometers for liquid samples have been constructed, working at 7, 9.2 and 14 T, respectively. ? The field dependence of the Overhauser DNP efficiency has been measured experimentally for the first time up to a field of 9.2 T and compared with experimental results from NMRD, MD and theoretical models. ? Coherent and relaxation effects within fast magnetic field changes have been observed and quantitatively analyzed. ? High Overhauser DNP enhancements for liquid samples have been observed at high magnetic field.

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....

Sensitive 13Câ??13C correlation spectra of amyloid fibrils at very high spinning frequencies and magnetic fields
Abstract Sensitive 2D solid-state 13Câ??13C correlation spectra of amyloid β fibrils have been recorded at very fast spinning frequencies and very high magnetic fields. It is demonstrated that PARIS-xy recoupling using moderate rf amplitudes can provide structural information by promoting efficient magnetization transfer even under such challenging experimental conditions. Furthermore, it has been shown both experimentally and by numerical simulations that the method is not...
