The ability to directly measure and evaluate ultrafast processes with unprecedented time resolution and reliability has greatly extended our knowledge about the kinetics of primary processes in chemistry and allied physical and biological sciences. Improvements in the reliability and versatility of picosecond techniques should lead to an increase in the experimental information about basic interactions in atomic and molecular systems.
