## Abstract Insight into the unique structure of hydrotalcites has been obtained using Raman spectroscopy. Galliumβcontaining hydrotalcites of formula Mg~4~Ga~2~(CO~3~)(OH)~12~Β· 4H~2~O (2:1 GaβHT) to Mg~8~Ga~2~(CO~3~)(OH)~20~Β· 4H~2~O (4:1 GaβHT) have been successfully synthesized and characterized

## Abstract Insight into the unique structure of layered double hydroxides has been obtained using a combination of Xβray diffraction and Raman spectroscopy. Indiumβcontaining hydrotalcites of formula Mg~4~In~2~(CO~3~)(OH)~12~Β· 4H~2~O [2:1 InβLDH (layered double hydroxides)] through to Mg~8~In~2~(C
Raman microscopy has been used to characterize the interlayer anions in synthesized hydrotalcites of formula Mg 6 Al 2 (OH) 16 (XO 4 )β’4H 2 O, where X is S, Mo or Cr. The Raman spectrum shows that both the chromate and molybdate anions are not polymerized in the hydrotalcite interlayer. This lack of
