Abstract
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 9.2 T. 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.
