Abstract
The lattice contribution to the diamagnetic susceptibility, , is written as a sum of three terms, a core term , a Langevin-like valence-electron contribution , and a Van Vleck paramagnetic term using a one-oxcillator model. Measurements of and for diamond, Si, Ge, GaAs, and GaP are presented. The model allows a separate determination of each of the three terms and relates these terms to the symmetry and extent of the valence-bond charge distribution.
