In this complex, there are two optically active sites. Spinach plastocyanin is a type I copper protein, in which two reactive sites have been identified on its surface, at least. The electron transfer reaction occurs with significantly large stereoselectivity the ratio of the observed reaction rate constant (k /k ) is 1.6 to 2.0. The difference in the activation enthalpy, AAH a, is 3.0 kJ mol-1, and the difference in the activation entropy, AS (a-a) is 15 J mol-1 K-1. This means that the stereoselectivity arises from the entropy term. 

The bond distance is taken from Brewer et al. (3 ). The bond distances for all of the transition metal difluorides from chromium through copper were estimated to be the same with the assessment that an error of 0.5 A would lead to an error of less than 1 cal K" mol" in the entropy. The bond angle and vibrational frequencies are those derived by Hastie et al. ( ) from infrared studies of matrix-isolated isotopic species. The electronic states and levels are assumed the same as those assigned to... 

Many of the new tasks would be at the boundary with materials science. There are some that are obviously applications-oriented, like the electronic theory of high temperature superconduction in the layered copper-oxide perovskites, and other aspects of nanotechnology. There are also fundamental valence problems, such as accounting for the structures and properties of quasiciystals. Why is the association of transition metals and aluminium apparently of central importance How do we deal with the valence properties of systems where the free energy of formation or phase transition is dominated by the entropy term ...
