Henry Taube and the Mechanisms of Electron-transfer Reactions

Henry Taube and the Mechanisms of Electron-transfer Reactions

Harald Sack
On November 30, 1915, Canadian-born American chemist Henry Taube was born. Taube has been awarded the 1983 Nobel Prize in Chemistry for his extensive research into the properties and reactions of dissolved inorganic substances, particularly oxidation-reduction processes involving the ions of metallic elements. Metals often form complexes, in which other atoms cluster around the metal atom, transferring and sharing electrons among themselves to bind together. Taube discovered that during a reaction, a…
