Abstract
Enhanced nuclear polarization of a magnetic resonance sample provides greater detection sensitivity over conventional NMR spectroscopy due to a method and an apparatus of increasing the detection sensitivity. Molecules capable of forming photo-excited triplet states are combined in a solution with a NMR sample. While in a uniform magnetic field the solution is frozen, optical radiation is applied to produce photo-excited triplet states molecules and a microwave radiation is applied to stimulate transitions of one of the triplet lines producing dynamic polarization of the nuclei in the magnetic resonance sample. The frozen sample is then rapidly melted and a NMR analysis is performed.
