Time-resolved spectroscopy of condensed phase rearrangements is discussed and illustrative examples are presented. A femtosecond pulse initiates phase-coherent nuclear motion in nearly any medium through which it passes, through either optical absorption or impulsive stimulated light scattering. Acoustic phonons, optic phonons, molecular vibrations, or other types of motion may be driven. Once initiated, these motions can be monitored in real time with additional short pulses. In some cases the motion underway may lead to chemical or structural rearrangement of the sample. Examples of structural phase transitions, chemical reactions, and molecular dynamics in the liquid state are discussed.
