The contribution of the ligands around Cr to the resonant inelastic L X-ray emission spectra

Abstract L X-ray emission spectra in the energy region of the Cr 2p threshold on Cr compounds were measured and analysed using tunable synchrotron radiation. The X-ray absorption and emission spectra (XAES) of Cr (VI) are very different from those of Cr (III). It is considered that the difference in the soft X-ray emission is mainly attributed to the effect of the covalency in bonding, because the transition intensity of the Kβ 2 spectral line is sensitive for the valence electronic configuration. Therefore, it follows that XAES is very sensitive to the ligand environment in Cr compounds and relatively insensitive to the metal oxidation state, as Grush et al. suggested for Mn complexes [J. Electron. Spectros. Relat. Phenom. 92 (1998) 225].
