ABSTRACT:
A nuclear magnetic resonance apparatus includes a nuclear magnetic resonance device for elucidating atomic configuration and molecular structure of a substance based on a decay signal of induced electromotive force caused by resonance precession of nuclear magnetic moment induced by irradiation of electro-magnetic pulses in an RF region when the substance is exposed to a strong magnetic field, and a vibration isolation mechanism for suppressing vibrations. The vibration isolation mechanism has, as an actuator, an air spring connected to a pressurized air source via an electro-pneumatic converter and acting to exert a force for vibration isolation on the nuclear magnetic resonance device. The vibration isolation mechanism is capable of active vibration isolation, and disposed away from the nuclear magnetic resonance device by such a distance that the electro-pneumatic converter never incurs any malfunctions or operating failures under influence of a magnetic field generated by the nuclear magnetic resonance device.
