Abstract
A theoretical description of Mossbauer relaxation spectra of the Fe(II I) high-spin ion is presented for the general case of rhombic symmetry . A least-squares fit of Mossbauer spectra of the Superoxide Dismutase of Propioni bacterium shermanii subspec. freudenreichii (SOD) is give n using this theory. It is shown that an isotropic relaxation model is a sufficiently good model to describe the temperature dependence of t he Mossbauer spectra.
