Charles Alfred CoulsonBorn 13 Dec 1910; died 7 Jan 1974 at age 63. British theoretical chemist known for the application of molecular orbital theory to chemical bonding, the electronic structures of molecules and the concept of partial valency. He developed many mathematical techniques for solving chemical and physical problems. His molecular orbital theory treats a molecule as a whole, and extends atomic quantum theory with “allowed” states of electrons associated with two or more atomic nuclei. With this approach, he explained the structure of benzene and other conjugated systems, and using what he called partial valency, he described the bonding in such compounds as diborane. After writing on Waves (1941) and Electricity (1941), his book Valence (1952) was highly influential. He also wrote on reconciling scientific and religious views, believing religious faith was an essential in the pursuit of science.« |
