Abstract
In this work, iodine L 1 -XANES of (CHI 0.02 ) x excited by two linearly polarized X-ray are analyzed by use of the short-range order full multiple scattering calculations. The XANES analysis for E ⊥ c polarization gives us the information on the I – C correlation. One useful information obtained here is that the nearest I – C distance is longer than the sum of the van der Waals radii of I and C . This result can explain the increase of the anisotropy of the electric conductivity with iodine doping. Our XANES analyses also confirm the charge distribution on polyanions I 3 - and I 7 - determined by Mössbauer spectroscopy.Keywords
