Abstract

In Chapter 6 we saw that the energy of the optical transition (hv max) between the highest occupied and lowest empty π orbitals (ππ* transition) of aromatic molecules decreased rapidly with increasing pressure. Similarly, the optical absorptions associated with electron transfer between a donor and acceptor frequently decreased with increasing pressure. The theory of Chapter 3 indicated that a moderate decrease in this energy might be sufficient to permit thermal occupation of the excited state at high pressure, especially when configuration interaction and related effects were considered. In Chapters 6, 8, 9, and 10 we saw that for a variety of systems this thermal occupation was highly probable at high pressure, and that these electronic transitions led to new spin states and oxidation states for iron, particularly when complexed to aromatic or quasi-aromatic molecules.
