Abstract:
1. A nuclear magnetic resonance spectrometer, comprising: a split-type superconducting magnet including a first coil formed on a first frame and a second coil formed on a second frame installed in opposition to the first frame, the magnet applying a static magnetic field in a first direction; a device for moving a sample in a direction crossing the first direction at right angles, and transporting the sample to a predetermined position between the first and second coils; a probe installed so that it extends in the first direction in a region including the center axes of the first and second coils; and a receiver coil, a transmitter coil and a probe coil having coil support materials that support the coils installed at the probe tip, wherein the coil support materials include a main part surrounded by members having two flat surfaces which are parallel and opposite to each other and two curved surfaces connected respectively to the two flat surfaces, a first fixing plate connected to one of the flat surfaces by an attachment member, and a second fixing plate connected to the other flat surface by an attachment member, the receiver coil is arranged inside a hole which passes through the first and second fixing plates, and the members having the first and second flat surfaces, respectively, the transmitter coil is formed in the main part surrounding the receiver coil, and the normal to the contact surface between the fixing plates and the main part is arranged to cross magnetic force lines of the static magnetic field at right angles.
