Abstract
A method is proposed for determination of the number of nuclei contributing to a particular line in a resonance spectrum. The method exploits the maximum signal-to-noise (S/N) ratio of which the system is capable and is based on an examination of the saturation properties of the absorption line. This provides an advantage over methods which measure simply the integrated intensities and which are correct only at low rf power levels, where the S/N ratio is correspondingly low. The procedure is successfully applied to some pure metal spectra.
