✦ Synopsis
The effect of orbit-lattice interaction which produces a mixing between the low-lying electronic states with the emission and absorption of phonons of varying energies is considered to explain the observed temperature dependence of Mossbauer quadrupole splitting of "Fez' ions in Fe[(CH,)zSO],(CIO,)z. The various lattice dynamical parameters are estimated and then quadrupole splitting is explicitly calculated as a function of temperature. One obtains a reasonably good agreement with the experimental data which shows that the vibrating lattice model is quite realistic and important.
