| Abstract: | The IR spectra of polycrystalline Mg(OH)2 and Mg(OD)2 are reported in the 4000–40 cm−1 region. Band assignments were discussed on the basis of isotopic band shifts of the fundamental vibrations by combining the results of factor group analysis for D3d3 crystal structure with the Teller–Redlich product rule for crystal vibrations. The band assignments proposed are different from the previous IR spectroscopic studies. |
