Abstract

In this paper we investigate a novel set of polarizing agents --\nmixed-valence compounds -- by theoretical and experimental methods and\ndemonstrate their performance in high-field Dynamic Nuclear Polarization (DNP)\nexperiments in the solid state. Mixed-valence compounds constitute a group of\nmolecules, in which molecular mobility persists even in solids. Consequently,\nsuch polarizing agents can be used to perform Overhauser-DNP experiments in\nsolid-state, with favorable conditions for dynamic nuclear polarization\nformation at ultra-high magnetic fields.\n
