Time-resolved techniques are methods used to study dynamic processes by capturing changes over time. These techniques allow scientists to observe how systems evolve, such as the behavior of molecules during chemical reactions or the movement of electrons in materials. By taking measurements at very short intervals, researchers can create a detailed timeline of events. Common time-resolved techniques include time-resolved spectroscopy and pump-probe experiments. In time-resolved spectroscopy, light is used to excite a sample, and the emitted light is analyzed to understand the dynamics of the system. Pump-probe experiments involve using two laser pulses to initiate and then probe a reaction, providing insights into ultrafast processes.
