摘要：

For [Fe3O(OOCCD3)6(C5H5N)3](C5H5N) elastic and quasielastic incoherent neutron scattering measurements are shown to give information on structural reorganization and molecular motions which correlates well with data derived from heat capacity measurements. Phase changes are identified, and clear evidence is obtained for a large increase in molecular motion between 200 and 300 K.
