Description
We analyse the manner in which local atomic structure affects the identification of Bi valence states in the x-ray absorption near-edge structure (XANES) of the Bi L3 edge, by comparing simulations of the Bi L3 edges in various polymorphs of Bi2O3, NaBiO3 and Ag25Bi3O18. We find that while the XANES is certainly sensitive to the ionicity of Bi, it is better described in terms of its sensitivity to the local bond lengths and coordination associated with the valence states of Bi
