Polarized Protons Domains in Matter

Domains of polarized protons have been created around paramagnetic centers in alcohols by dynamic nuclear polarization (DNP) methods, rf saturation and/or adiabatic fast passage polarization reversal. The decay of the polarization gradient has been indirectly observed by NMR methods.

We aim at taking advantage of the possibility to create such clusters of polarized protons in organic materials in order to investigate with higher resolution at will different parts of complex macromolecules by polarized neutron scattering.
