Pauhng, Linus

American chemist Irving Langmtiir (1881-1957) proposed that many chemical facts could be coordinated by applying these new ideas. Others followed by suggesting that a bond is a balance between nucleus-nucleus and electron-electron repulsions and electron-nuclei attractions. American chemist Linus Pauhng (1901-1994) assembled these ideas in his seminal book. The Nature of the Chemical Bond.

Included as Part V (Chapter 18) is a short, science-oriented biography of Pauhng by Prof. Jack Dunitz. At the end of Part III, and again at the end of Part IV, is a group of photographs of Linus Pauling with coUeagues/co-authors of the period. 

Photo 23 Linus Pauhng with Robert B. Corey at about the time the a-helix and other protein structures were discovered (Chapter 13), in the early 1950 s. Corey s specialty played a crucial role in these discoveries. He determined by x-ray diffraction the structures of amino acids, peptides, and other molecules derived from or related to proteins (SP 99, SP 105, SP 106).

As defined by Linus Pauhng, Chemistry is the science of substances their stmcture, their properties, and the reactions that change them into other substances [1]. The first aspects, structure and properties, are clearly associated with the arrangement of atoms in a molecule, i.e. the chemical bond. These bonds determine Pauhng s third aspect, chemical reactivity. In other words, chemical bonds are the undisputed foundation of chemistry and their visualization should allow chemists to understand how molecules behave at the most fundamental level.
