Vibrational spectroscopic studies of trivalent hexa-aqua-cations: single-crystal Raman spectra of caesium aluminium alums between 300 and 1 200 cm–1

Abstract

Oriented single-crystal Raman spectra of CsAl(SO4)2·12H2O, CsAl(SeO4)2·12H2O, and CsAl(SO4)2·12D2O have been recorded at 80 K. A complete assignment of the spectra has been made between 300 and 1 200 cm–1 using factor group analysis. All external modes of co-ordinated water for both [Cs(OH2)6]+ and [Al(OH2)6]3+ have been identified. The wavenumbers of the internal modes of [Al(OH2)6]3+ are ν1= 542 cm–1 and ν2= 473 cm–1, with ν5 centred at 347 cm–1.
