Polanyi, John C.

▪ Canadian chemist and educator
in full  John Charles Polanyi  
born Jan. 23, 1929, Berlin, Ger.

      chemist and educator who, with Dudley R. Herschbach (Herschbach, Dudley R.) and Yuan T. Lee (Lee, Yuan T.), received the Nobel Prize for Chemistry in 1986 for his contribution to the field of chemical-reaction dynamics.

      Born to an expatriate Hungarian family, Polanyi was reared in England and attended Manchester University (Ph.D., 1952; D.Sc., 1964). He accepted a research position with the National Research Council of Canada in 1952 and began teaching at the University of Toronto in 1956, accepting the title of university professor in 1974.

      Polanyi developed a technique that is known as infrared chemiluminescence based on the observation that molecules, when excited, emit infrared light. By means of spectroscopic analysis of the changes in emitted light that take place during a chemical reaction, he was able to trace the exchange of chemical bonds, thus helping to detail the disposal of excess energy that occurs during the process of chemical reaction.
