Electronic absorption spectra of palladium(II) ions in molten eutectic mixture of lithium, potassium and cesium chlorides.

Electronic absorption spectroscopy was used to assess palladium speciation in fused alkali chlorides. Electronic absorption spectra of palladium (II) chloro-ions were recorded in molten LiCl–KCl–CsCl eutectic mixture at 300–800 °C. Experimental spectra were resolved into individual bands for more accurate determination of the energy of electronic transitions. Increasing temperature resulted in decreasing absorption and ligand field splitting parameter Δ. [ABSTRACT FROM AUTHOR]
