Raman and IR spectra of Bi 2 W 2 O 9 , the m = 2 member of the cation‐deficient Aurivillius phase, have been measured. The obtained spectra are discussed using the factor group approach for the orthorhombic Pna 2 1 ( C 2 v 9 ) space group. The results are compared with those obtained for Bi 2 WO 6 and some m = 2 members of Aurivillius family of bismuth layered ferroelectrics. Copyright © 2009 John Wiley & Sons, Ltd.
