Spectral analysis

The near-edge structure (XANES) of an X-ray absorption spectrum can be used to discuss the local chemical environment of the absorbing atom. The thirteen questions below are grouped as structure and speciation, quantitative analysis, and how a spectrum changes. The thirteen questions Approach What is observed Example or question Coordination edge and near-edge shape separate valence, coordination number, or geometry Crystallinity spectral shape crystalline versus amorphous $\mathrm{SiO...
