Time-Resolved Spectroscopy is a technique used to study the dynamics of chemical and physical processes by measuring how light interacts with matter over very short time scales. It allows scientists to observe changes in a sample as they happen, providing insights into reactions, energy transfer, and molecular movements. This method typically involves using short pulses of light, such as those from a laser, to excite a sample. By analyzing the emitted light at various time intervals, researchers can gather information about the speed and mechanisms of processes like photosynthesis or chemical reactions, enhancing our understanding of fundamental science.
