In order to determine the behavior of the Fe2+ site as a function of the absorbed dose, we measured fluorescence-detected XANES spectra as a function of the X-ray flux, both in PVA films and dry trehalose matrices at room temperature and in the dark. No changes were observed in the XANES spectra of RC in PVA as a function of the absorbed dose, to the contrary of what was expected on the basis of preliminary measurements. A detailed data analysis allowed us to determine with a high resolution the local structure around Fe for the RC embedded in both in trehalose in the PVA matrix.

Abstract

In order to determine the behavior of the Fe2+ site as a function of the absorbed dose, we measured fluorescence-detected XANES spectra as a function of the X-ray flux, both in PVA films and dry trehalose matrices at room temperature and in the dark. No changes were observed in the XANES spectra of RC in PVA as a function of the absorbed dose, to the contrary of what was expected on the basis of preliminary measurements. A detailed data analysis allowed us to determine with a high resolution the local structure around Fe for the RC embedded in both in trehalose in the PVA matrix.
