This method measures X-ray absorption caused by the excitation of a metal 2p electron to unfilled d orbitals (e.g. 3d for first-row transition metals), which creates a characteristic absorption peak called the L-edge.

Since RIXS accesses more final states than L-edge XAS, while L-edge XAS more clearly probes the π* back-bonding peaks, the two methods provide complementary information and thus very detailed experimental electronic structure insight when analyzed together.

A series of mononuclear V (V), V (IV) and V (III) complexes were investigated by V L-edge near edge X-ray absorption fine structure (NEXAFS) spectroscopy. The spectra show significant sensitivity to the vanadium oxidation state and the coordination environment surrounding the vanadium center.

2021年6月11日 · Here, we report the development of a database of computed L-edge XANES using the multiple scattering theory-based FEFF9 code. The initial release of the database contains more than 140,000...

2021年11月25日 · Two peaks located at ~518 eV and 525 eV are observed in the V L-edge pattern, corresponding to V 2p 3/2 → V 3d and V 2p 1/2 → V 3d transitions, respectively 51,52.

The O K-edge and the V L 2,3-edge NEXAFS spectra of V 2 O 5 were calculated on the basis of the newly developed Restricted Open shell Configuration Interaction with Singles (DFT-ROCIS) method. In this study the applicability of the method is extended to the field of solid-state catalysis.

... the V L-edge includes two main peaks, which are L 3edge (515-520 eV) and L 2 -edge (520-528 eV), corresponding to the V 2p 3/2 to V 3d and V2p 1/2 to V 3d dipole allowed transition,...

2p (L 2,3) X-ray absorption spectra are presented for a range of minerals to demonstrate the usefulness of L-edge spectroscopy as a symmetry- and valenceselective probe. 2p XAS provides a sensitive fingerprint of the electronic states of 3 d transition metals and can be applied to phases containing mixtures of such elements.

Here, we report the development of a database of computed L-edge XANES using the multiple scattering theory-based FEFF9 code. The initial release of the database contains more than 140,000...

2012年1月5日 · BaVS 3 single crystal V L edge x-ray linear dichroism (LD) spectra show changes with temperature. Below 150 K there is a clear LD intensity increase at 513.2 and 515.8 eV.
