Mixed-valence compounds as polarizing agents for Overhauser dynamic nuclear polarization in solids.

摘要: In this paper we investigate a novel set of polarizing agents - mixed-valence compounds by theoretical and experimental methods demonstrate their performance in high-field Dynamic Nuclear Polarization (DNP) NMR experiments the solid state. Mixed-valence constitute group molecules, which molecular mobility persists even solids. Consequently, such can be used to perform Overhauser-DNP solid-state, with favorable conditions for dynamic nuclear polarization formation at ultra-high magnetic fields.
