Ultrafast spectroscopy is a powerful experimental technique used to study the dynamics of chemical and physical processes on extremely short timescales, often on the order of femtoseconds (10^-15 seconds) to picoseconds (10^-12 seconds). It typically involves the use of short laser pulses to excite a sample and then probe the time-evolution of its electronic and molecular properties.
