During the last twenty years sophisticated microscopic experimental techniques and large‐scale theoretical computations have significantly enhanced our understanding of the detailed dynamics of chemical reactions. The development of computer codes to perform lengthy and detailed computations has made it possible to clarify the connection between the first principles of quantum chemistry and the behavior of substances in the real world. Modern spectroscopy, laser technology and molecular‐beam methods allow us to observe chemical reactions on the atomic and molecular levels in great detail.
