Abstract This paper describes a systematic study of the spectra and local structures of lanthanide (Ln) L‐edge XANES. We found that Ln L 1 and L 3 ‐edge XANES spectra exhibit characteristic features correlated to their local symmetry through experimental and theoretical simulations. We also propose a simple local structure index criterion for a combination of XANES study and theoretical simulation. Possible solutions of intrinsic problems such as low resolution of characteristic features in the Ln L‐edge XANES and site distributions are also discussed.
