ABSTRACT:
A nuclear magnetic resonance probe incorporating at least two bottles with radical solutions, one having a positive nuclear polarization and the other a negative nuclear polarization, at least one high frequency coaxial resonator around each bottle respectively, an assembly of low frequency exciting-sampling coils. The coil assemblies are interconnected and connected to an amplifier in a loop oscillator connection. The probe comprises two blocks having a symmetry of revolution with respect to one axis and a symmetry with respect to a plane perpendicular to the axis of revolution. Each block incorporates at least one bottle having a shape of revolution about the axis and is symmetrical with respect to the plane of symmetry and a coaxial resonator having the same symmetries as the bottle. Each block contains the bottle, a double frequency coil of revolution about the axis and completely surrounds the resonator and the bottle. Each block is formed from two coils of revolution facing one another on either side of the plane of symmetry of the block. The two coils are interconnected.
