Raman study of alcoholic solutions of anhydrous rare earth chlorides

摘要

Raman Ln-CI stretching spectra (Ln=rare earth ion) were measured for alcoholic solutions (alcohol=methanol, ethanol and n-propanol) of anhydrous rare earth chlorides. From the extended s-shaped variation of the frequency for the Ln-CI stretching Raman band across the series, it is concluded that the inner-coordination number of rare earth ions decreases by one in the latter region of the rare earth series.
