Abstract
Brillouin scattering is used to determine the elastic constants of the incommensurate inclusion compound of dioctanoyl peroxide and urea. The results are interpreted in terms of a simple microscopic model, based on the crystal structure of this compound. A detailed discussion is given concerning the absence of effects in Brillouin scattering due to the sliding (or Goldstone) mode. This kind of mode is expected to be present in incommensurate intergrowth compounds.Keywords
