✦ Synopsis

It is demonstrated that it is possible to observe nuclear spin noise at room temperature using a conventional NMR spectrometer. The noise spectrum shows the impedance characteristics of the receiver circuit modified by the presence of the nuclear spins and manifests spontaneous emission of spin noise. The experimental findings are compared with analytical results derived from a simple electronic circuit model. The role of radiation damping in determining the features of spin noise is discussed.
