By calculating the vibrational entropy change during hole transition for Fe-center, it is shown that the acceptor state of Fe-center is antibonding; The enthalpy and Gibbs free energy change and their temperature dependence caused by hole transition are calculated and compared with experimental data. From the results, it is reasonably well understood that activation energy obtained by thermal emission rate for Fe-center is always larger than that from optical measurement.
