The authors present a theoretical study of dipolar broading of the NMR absorption spectrum for a solid nonmagnetic host with spin 1/2 impurities randomly placed on a SC lattice. An iterative procedure is developed to separate the broadening into homogeneous and inhomogeneous components. Their results indicate that even in the dilute limit both forms of broadening are present. An information theoretic Maximum-Entropy technique is used to reconstruct the homogeneous component of the line shape from calculated moments, and a version of Anderson's Statistical Theory is employed to obtain the inhomogeneous component. Results are presented for all concentrations, and are easily generalized to any well defined structure.
