Abstract

Temperature-dependent 57Fe Mossbauer effect spectroscopy has been used to characterize the hyperfine and dynamical properties of the metal atom in two crystallographic forms of ferrocenium hexafluoroarsenate. The temperature dependence of the recoil-free fraction and the spin-lattice relaxation rates have been determined over the interval 89
