(James A. Ibers et al., "Proton magnetic resonance...)

The general theory of resonance shifts is used to derive a general expression for the second_moment **f of a polycrystalline paramagnetic sample and is specialized to **f .

The experimental second_moment **f conforms_to the relation **f in_agreement with theory .

Second_moments of the spectra were computed by numerical integration .
