Polarization dependent iodine K-edge XANES spectra of iodine-doped polyvinyl alcohol (PVA) films provide much information on the local structure around iodine anion. The present multiple scattering analyses support that the iodide anions are along to the PVA chain in the films. The difference XANES spectra taken between 0° and 90° and between 45° and 90° are slightly sensitive to the local structure of the PVA film around iodine anions.
