Used in print (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 . Related terms
