| Popis: | A calculation of the circular dichroic signal in the attenuation coefficient of a two-iron cluster is used to demonstrate the potential ability of soft x-ray absorption spectroscopy to give quantitative information very directly on its magnetic state. The analytic calculation is based on a ligand-field model that has been successfully used to interpret EPR data on a large number of ferredoxins. Our findings are compared, with some success, to empirical results for the dichroic signal of c. pasteurianum ferredoxin obtained from the total fluorescence yield. |
