Dudley, John

Usually we talk about reactions in solution, but recently techniques have been developed to follow reactions that occur in a vacuum when a stream of reactant A and a stream of reactant B cross each other in a defined direction, as with molecular beams. From the direction in which the products are ejected and their energies, much fundamental information can be deduced about the details of the molecular processes. Lasers, which emit light-energy in a highly focused beam, are sometimes used to put energy into one of the reactants in a defined way. Such a technique reveals less about the nature of the transition state than about what is called the dynamics of the process—how molecules collide so as to react, and how the products carry away the energy of the overall reaction. The development and application of such techniques were recognized by a Nobel Prize in 1986 to Dudley Herschbach, Yuan Lee, and John Polanyi.

LEE, YUAN T. (1936-). Awarded the Nobel prize in chemistry in 19X6 jointly with John C. Polanyi and Dudley R. Herschbach for their contributions concerning the dynamics of chemical elementary processes. A former student of Herschbach. Lee relined molecular-beam and laser techniques, comhining them with theory to perform definitive studies of reactions of individual complex molecules. Lee received his Doctorate from the University of California at Berkeley in 1965. 

In 1994 on the occasion of Herzberg s ninetieth birthday, the Canadian Journal of Physics published a special issue. The festschrift, edited by Donald Betts and John Coxon of Dalhousie University, contains 72 papers by many of the world s leading spectroscopists and theoretical chemists. In his acknowledgment, Nobel laureate Dudley Herschbach summarized Herzberg s inestimable impact with the following tribute 4... 

Molecular beams are very important tools for characterizing intermolecular and intramolecular reactions. In fact, the 1988 Nobel Prize in Chemistry was awarded to Yuan Lee, Dudley Herschbach, and John Polanyi for studies which were mostly made possible by this technique. A particularly useful variant is the supersonic molecular beam, which in the simplest case pushes a high-pressure mixture of helium and trace amounts of some larger guest molecule through a nozzle. When the helium atoms enter the... 

John C. Polanyi (b. 1929 in Berlin) is University Professor at the Department of Chemistry, University of Toronto, Toronto, Canada. Dudley R. Herschbach (b. 1932), Yuan T. Lee (b. 1936), and John Polanyi received jointly the chemistry 1986 Nobel Prize for their contributions concerning the dynamics of chemical elementary processes. ... 

Michael Polanyi was an early influence on Dudley Herschbach. He cherishes the memory of all his five meetings with Polanyi. The first time they met was in 1962 when Michael Polanyi came to Berkeley to give some lectures. Polanyi visited Herschbach s laboratory and Polanyi was telling him stories about his son John. Polanyi was surprised that John became a scientist because, he said, John in his teenage years used to bitterly criticize his father, saying that he was writing papers, all the time, that were not connected with the real world.

John C. Polanyi (1929- ) was born in Berlin to parents of Hungarian descent. His father, Michael Polanyi, developed transition state theory (see chapter 4) and also studied collisions between alkali metals and halogen molecules. The Polanyi family left Germany in 1933 for England where John received his education. He joined the University of Toronto in 1956 and used IR chemiluminescence, pioneered by his father, to study molecular collisions. In 1986, Dudley R. Herschhach, Yuan T. Lee, and John C. Polanyi shared the 1986 Nobel Prize in chemistry for the contributions to reaction dynamics.
