In the present work, the infrared (IR) and Raman spectra of 2,2′,4,4′-tetrabromodiphenyl ether have been measured in the ranges of 400–4000cm −1 and 100–4000cm −1 . The geometry optimized by the density functional theory Becke-3-Lee-Yang-Parr (B3LYP) method with the 6-31G(d) basis set was in good agreement with the experimental data of analogues. The results have shown that the dihedral...
