Electron Transfer

  • Keitaro Yoshihara

Abstract

Electron transfer (ET) is one of the most important processes which give functionality to molecular systems. There are nationally occurring molecular systems which involve electron transfer, such as photosynthetic systems in plants. Animal metabolism is another example where ET plays an important role, and it also occurs in a wide range of phenomena such as organic and inorganic chemical reactions, molecular conductivity, photography, and electrochemical processes. Because of its universality, ET has been the subject of extensive research for many years [1–4].
