Abstract
A probe for a nuclear magnetic resonance apparatus comprises: a transmission coil for irradiating a sample with a high-frequency electromagnetic wave; and a receiving coil for detecting a nuclear magnetic resonance signal emitted by the sample, wherein a selector switch is disposed to the transmission coil to reduce the deterioration of sensitivity of the receiving coil by switching the resonance state of the transmission circuit between during irradiation and during detection, even if an electromagnetic coupling remains between transmission and reception.
