Ab initio calculated XANES and XMCD spectra of Fe(II) phthalocyanine [link]Paper  doi  abstract   bibtex   
We report a density-functional calculation that predicts for iron(II) phthalocyanine (FePc) an unusual orbitally degenerate intermediate-spin ground state 3Eg. The calculated Fe L2,3 near-edge x-ray absorption spectrum agrees reasonably with experiment, whereas the presence of an unquenched orbital moment is corroborated by a recent discovery in α-FePc of a very large hyperfine field of positive sign [Filoti et al., Phys. Rev. B 74, 134420 (2006)]. It is suggested that the orbital moment of FePc should be observed more directly in x-ray magnetic circular dichroism experiments.
