FTIR study of matrix-isolated halides of dysprosium and thulium and their gaseous heterocomplexes with alkali halides
- Univ. La Sapienza, Rome (Italy)
Vibrational spectra of dysprosium and thulium chlorides, bromides, and iodides isolated in argon have been studied for the first time. The appearance of a single band, even in heavy deposits, suggested a planar geometry for all the samples examined. The complexity of Dy and Tm chlorides spectra, partly because of isotopic patterns, required a reinvestigation of NdCl{sub 3} isolated in argon and have been explained by comparison. Vapors in equilibrium over heated equimolar mixtures of a number of Dy, Tm, and Nd halides with alkali halides trapped in argon have been also investigated. FTIR measurements gave experimental evidence for the formation of gaseous heterocomplexes whose geometry is discussed.
