The authors study the molecular motion of ferrocene Fe(C{sub 5}H{sub 5}){sub 2} locked up in the supercages of KY zeolite at temperatures 22 K {le} T {le} 238 K by means of quasielastic neutron scattering. The geometry of the motion is determined to be a 5-fold internal jump reorientation of the cyclopentadienyl C{sub 5}H{sub 5} rings around the symmetry axis of the ferrocene molecule. The mean residence time was obtained for these jumps as well as the activation energy for the process. A comparison was made of NMR results on ferrocene in faujasite-type zeolites and quasielastic neutron scattering results on pure ferrocene.
