| Abstract: | FTIR reflection spectra of molten chloroaluminates containing alkali earth chlorides showC2v andC3v perturbations of AlCl4–. The splitting ofv3(F2) is proportional to the ionic potential of the counterion. The observation of anion-cation stretching vibrations allows the strength of the interaction to be evaluated. Molten NaAl2OCl5 is assumed to contain the Al4O2C1102– ion. |
