Abstract
A method of polarizing nuclei having a long relaxation time in a solid in a high DC magnetic field. The solid also contains nuclei having a short relaxation time. The method involves the step of applying a high DC magnetic field to the solid. Then the solid is swept with a radio frequency field which excites the nuclei with a short relaxation time thereby resulting in the polarization of the nuclei having a long relaxation time.
