“…The spin-orbit interaction in the 3d shell has been neglected. Their calculated spectra agree well with the measurements in [14] on 3d transition-metal fluorides, although it is clear that in some cases they have overestimated the covalency. Good agreement was also found with the results in [15] in which the multiplet structure of core p vacancy levels for 3d transition metal ions is calculated, with the inclusion of spin-orbit interactions but excluding the crystal-field effect.…”

The electron energy loss and x-ray absorption spectra of two phases of titanium dioxide-rutile and anatase-are reported. Although the nearest-neighbour environments of titanium and oxygen in both these structures are very similar, noticeable differences are observed between the electron energy loss and the x-ray absorption spectra. Attempts to model these differences using real-space multiple-scattering calculations are reasonably successful at the Ti K and 0 K edges. We propose an interpretation of the Ti L2,3 edge, notably for the presence of a previously unobserved splitting on the L, edge.

“…Similar peaks were observed for the L 2 edge. This spectrum is totally different from the Fe L 2,3edge XA spectra of iron oxides28,29 and most Fe compounds [30][31][32][33][34]. In K 3 [Fe(CN) 6 ], a large peak attributed to the partially-unoccupied t 2g orbital appears at 706 eV, which is completely different from SNP and K 4 [Fe(CN) 6 ].…”

The electronic structure of Na2[Fe(CN)5NO]·2H2O (sodium nitroprusside: SNP) was investigated by using soft X-ray absorption (XA) spectroscopy. The Fe L2,3-edge XA spectrum of SNP exhibited distinct and very large satellite peaks for L3 and L2 regions, which is different from the spectra of hexacyanoferrates and the other iron compounds. A configuration-interaction full-multiplet calculation, in which the ligand molecular orbitals for the C4v symmetry were taken into account, revealed the Fe(2+) low-spin state with very strong effects of metal-to-ligand charge-transfer from the Fe 3d to NO 2p orbitals.

The Ba and Nd L2,3 X‐ray absorption spectra in ZrF4BaF2NdF3 and some ZrF4BaF2 binary glasses are studied. It is observed that the intensities of the white lines (WLs) in Nd and/or Ba L2,3 edges from these materials differ from those of their fluorides. Besides, the intensity ratios of the WLs in Ba and Nd L2,3 edges, L3/L2 deviate from the statistical value. These ratios for the studied glasses are also not the same as those from the corresponding fluorides. However, these changes of both the WL intensities and the ratios L3/L2 in Ba L2,3 edges differ from those in Nd L2,3 edges. These differences are discussed and attributed to the differing interaction between Ba or Nd and F in the glasses.
