Times Cited Count：0 Percentile：0(Physics, Applied)The electronic structure of the unoccupied conduction band of polycrystalline chloroaluminum phthalocyanine was investigated by X-ray absorption spectroscopy (XAS) near the Cl K-edge. XAS spectra were recorded in total electron yield (TEY) and partial Auger electron yield (AEY) modes. Partial AEY spectra were measured using normal and spectator Cl KL
L Auger yields as a function of photon energy. Although the TEY spectrum showed a broad shape; that was difficult to deconvolute curve fitting, the normal and spectator AEY spectra clearly showed that 
*(Cl-Al) transition splits into two competitive peaks attributed to the core excitons (localized with a core hole) and conduction band (delocalized without a core hole). The existence of a band-like peak in the Cl K-edge XAS is evidence that the Cl axial ligand participates in forming the conduction band. Thus, band-like electron transport is expected to occur in the oligomer-like (-Al-Cl-Al-) site.

Since a chloride ion is assumed to be one of the predominant solutes dissolved in groundwater, a study of the radiolysis of chloride ion and oxychlorides in aqueous solutions has been carried out in order to obtain the reliable and predictable data for the understanding the radiation induced reactions taking place in groundwater, relevant to the geological radioactive waste repository. The rate constants of the reactions between water decomposition products and different oxychlorides were determined by means of pulse radiolysis and laser photolysis methods. By using the techniques of photometry and ion-chromatography, the products formed by irradiation were analyzed and the overall reactions were summarized. After the comparison between the simulation and the experimental results, the redox reactions of the oxychloride compounds in aqueous solution were summarized and future work to be done has been pointed out.
