X-ray Absorption Near Edge Structure (XANES) is a spectroscopic technique used to determine local symmetry around a central metal atom. This part of the X-ray absorption spectrum focuses on the region near the absorption edge, including transitions into bound states. The energy required to promote an electron from its ground state to an excited orbital is indicative of metal ion oxidation state, and the intensity of these pre-edge transitions is often indicative of symmetry. Model compounds containing cobalt were investigated to define the correlation between the integrated area of the Co(II) 1s to 3d transition with the coordination number and environment of the cobalt center.
