Further measurements on single crystals of Cs2CoCl3 and Cs3CoCl5 to enlarge the knowledge of the electronic structure of the CoCl42- ion are presented. In the visible region, the spectra show better definition of the spin-forbidden band distribution arising from the two Ti quartet terms F-4 and P-4. Besides, measurements with X-ray photoelectron spectroscopy (XPS) and electron energy loss spectroscopy (EELS) allow one to (a) trace (in XPS) the density-of-states (DOS) of the valence orbitals and measure the first interband transitions as satellites near the main Co2p(3/2) peak; and (b) identify other interband transitions and several plasmons in EELS.

Abstract
Further measurements on single crystals of Cs2CoCl3 and Cs3CoCl5 to enlarge the knowledge of the electronic structure of the CoCl42- ion are presented. In the visible region, the spectra show better definition of the spin-forbidden band distribution arising from the two Ti quartet terms F-4 and P-4. Besides, measurements with X-ray photoelectron spectroscopy (XPS) and electron energy loss spectroscopy (EELS) allow one to (a) trace (in XPS) the density-of-states (DOS) of the valence orbitals and measure the first interband transitions as satellites near the main Co2p(3/2) peak; and (b) identify other interband transitions and several plasmons in EELS.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
