The prototypic phase of WO. is considered to be the tetragona[ phase withthe space group D'?., that is the highest temperature phase, to explain systemati-cally the displasive successive phase transitions of wo,.The normal modes at the points F, Z, M and A in the tetragonal Brillouin zoneare studied with the help of the group theory and are compared with the normalmodes in the cubic WO. that is the hypothetic prototype with the space group OJ.The condensed modes in each phase of WO. are described by the irreduciblerepresentations of the normal modes in the tetragonal W03, referring to theresults of X-ray and neutron diffraction studies.
