Chemical reactivity is currently explained in terms of several diverse
scientific traditions and Proton-Coupled Electron Transfer (PCET) is
central to these traditions, together with quantum mechanical tunnelling
of the electron particle. This book brings together all these traditions
through the authors' research and experience. It covers the most recent
developments in the field of PCET reactions, from the theoretical and
experimental points of view. It concentrates on the importance of PCET
in biological systems and for bioenergetic conversion, namely the
oxidation of water in Photosystem II, to produce oxygen, and the
reduction of protons to hydrogen by hydrogenase, for energy storage.
Furthermore, the book also brings together the most important chemical
explanations employed in this field.
