Multielectron Excitations in X-Ray Absorption Spectra of KOH

Multielectron Excitations in X-Ray Absorption Spectra of KOH

The X-ray absorption spectra have been measured near Kedge of a crystalline KOH. After the subtraction of XAFS oscillation, several features caused by multielectron transitions suggested on noble gases were detected on K in solid phase and analyzed by the use of the shakeup and shakeoff probabilities. The [ls2p], [ls3s], and [ls3p] transition onsets have been identified in the compound.

We calculate the x-ray absorption spectra (XAS) for 1s-π * and 1s-σ * transitions in single layer graphene using th...

Beyond the Pair Distribution Function in X-ray Absorption Spectra

Multiple-scattering calculations of x-ray-absorption spectra.

A high-order multiple-scattering (MS) approach to the calculation of polarized x-ray-absorption spectra, which includes both x-ray-absorption ne structure (XAFS) and x-ray-absorption near-edge structure (XANES), is presented. EEcient calculations in arbitrary systems are carried out by using a curved-wave MS path formalism that ignores negligible paths, and has an energy-dependent self-energy a...

pH-dependent x-ray absorption spectra of aqueous boron oxides.

Near edge x-ray absorption fine structure (NEXAFS) spectra at the boron K-edge were measured for aqueous boric acid, borate, and polyborate ions, using liquid microjet technology, and compared with simulated spectra calculated from first principles density functional theory in the excited electron and core hole (XCH) approximation. Thermal motion in both hydrated and isolated molecules was inco...
