X-ray Absorption Spectroscopy
X-ray absorptioń spectroscopy, today widely used as a tool for structural investigations, is described. Theoretically it is shown that above an absorption edge the absorption coefficient is well approximated by a sum of terms, each one describing a particular path followed by the photoelectron outgoing from the atom. Such geometrical feature allows to use X-ray absorption spectroscopy for struc...

متن کاملX - Ray Photoelectron Spectroscopy of Silicate Glasses
X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...
متن کاملHigh-resolution X-ray emission and X-ray absorption spectroscopy.
In this review, high-resolution X-ray emission and X-ray absorption spectroscopy will be discussed. The focus is on the 3d transition-metal systems. To understand high-resolution X-ray emission and resonant X-ray emission, it is first necessary to spend some time discussing the X-ray absorption process. Section II discusses 1s X-ray absorption, i.e., the K edges, and section III deals with 2p X...
متن کاملAn Angle-Resolved Photoelectron Spectroscopy and Near-Edge X-ray Absorption Fine Structure Study
The nature of the surface formed by a saturated layer (8(NO) = 1.0) of NO on a Mo(100) surface at 150 K has been determined by using both angle-resolved ultraviolet photoelectron spectroscopy and the angular variation of near-edge X-ray absorption fine structure (NEXAFS). Photoelectron spectroscopy indicates that NO can adsorb molecularly at this temperature but that a portion of the NO is also...
