This chapter introduces the concepts, theoretical approaches, and experimental techniques of ultrafast spectroscopy. By pushing the time resolution to a few femtoseconds the observation of atomic and molecular motions in real time becomes possible. This is illustrated by means of applications including molecular dynamics from isolated diatomics via clusters to biomolecules as well as processes in semiconductors and at surfaces. Perspectives are given on the emerging fields of attosecond physics and time-resolved diffraction techniques.
