Research documents and lectures of Dudley Herschbach, 1986 Nobel Laureate in Chemistry, are now posted at OSTI's DOE R&D Accomplishments website. Herschbach helped explain in detail how chemical reactions take place, and solved the problem of how to observe the random directions and velocities of molecules in a gas or a liquid (see Understanding Chemical Reactions at the DOE Office of Science website). Resources with additional information, including downloadable full-text documents, can be found at DOE R&D Accomplishments. You can also browse the database, read about other Nobel Laureates, and link to Enrico Fermi Award Laureates. DOE R&D Accomplishments is a central forum for information about the outcomes of past DOE R&D widely recognized as remarkable advances in science.
