From the expressions given for example in Refs. [4,9,29], it can be seen that the nuclear factor, and consequently the electron transfer rate, becomes temperature independent when the temperature is low enough for only the ground level of each oscillator to be populated (nuclear tunneling effect). In the opposite limit where IcgT is greater than all the vibrational quanta hco , the nuclear factor takes an activated form similar to that of Eq. 1 with AG replaced by AU [4,9,29]. The model has been refined to take into account the frequency shifts that may accompany the change of redox state [22]. 

Many of the factors which control the properties and chemistry of rare earth elements and compounds have been considered in Section 1.2 - rare earth elements and their place in the periodic system. These factors are electronic configurations, ionic radii, lanthanoid contraction and redox potentials/oxidation states (Table 1.1). Some general properties are listed in Table 1.1. For a more detailed account see refs 32-34.
