X-Ray Absorption Study of Iodine-Doped C60
X-ray absorption spectroscopy at the iodine LI,III — thresholds was applied to study the structural and chemical properties of iodine-doped C60. The studies were performed on a system of the chemical composition C60I3.66 prepared by gas-phase reaction. Both the iodine LIII — EXAFS and the LI — XANES prove the molecular form of the iodine as I2, modified by an increase in the intramolecular bond length upon intercalation. The derived chemical properties are similar to that of graphite intercalation compounds formed with halogen molecules.
