A continuum theory of long-wavelength non-polar acoustic and optical modes arising out of a microscopic model of the lattice dynamics is described. The chapter covers: microscopic model of the diamond lattice, equations of motion for acoustic and optical modes, decoupling of acoustic and optical modes, relation of elastic constants to bond strengths, lower symmetry for optical modes, and connection rules in nanostructures for acoustic modes different from those for optical modes.
