The diamagnetic species is converted to a paramagnetic species by electrochemistry. It is then possible to irradiate the EPR line to achieve Overhauser DNP and transfer part of the electron polarization to nuclei.

Abstract Dynamic Nuclear Polarization (DNP) studies of TANOL/water-glycerol solutions were per-formed at 1.53 mT. The samples have either various water-glycerol ratios at constant concentration or various concentrations at a constant water-glycerol ratio. The low field EPR spectra were recorded, the DNP parameters(enhancement factors, coupling constant, leakage factor) were determined, electronic relaxation times were measured. Depending on the values obtained, the interactions between nuclei and electrons are discussed.
