The wide-band nuclear magnetic resonance spectrometer is used for determining the NMR frequency of a sample in an external magnetic field and comprises a transmitter for generating a signal having a frequency equal to the NMR frequency of the sample. A receiver receives the signal from the sample and a probe is provided for applying the signal from the transmitter to the sample and from the sample to the receiver. The probe comprises a detector in the form of a tank circuit for detecting the signal of NMR frequency from the sample and for coupling the detector to the receiver and for substantially matching the impedance of the receiver.
