"Resonance in Every Position"

May 15, 2006

Linus Pauling (1901-1994). American chemist. Professor at the California Institute of Technology (1927-1962), and Nobel Prize winner for both chemistry (1954) and peace (1962). Though Pauling began his career as a crystallographer, he is best known for his work on the electronic theory of the chemical bond, as summarized in his 1939 monograph, The Nature of the Chemical Bond, and for his later work on the molecular and electronic structures of large biomolecules. His name is most often associated with his scale of ionic radii (1927), his rules for rationalizing the most stable structures for complex ionic crystals (1929), his extensive use of the both the hybridization (1931) and resonance concepts (1932) in chemical bonding, and his thermochemical electronegativity scale (1932). He also gained considerable notoriety for his political activism in support of nuclear disarmament, and for his controversial advocacy of the supposed medical benefits of megadoses of vitamin C.
