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