Time-resolved techniques refer to a set of experimental methods used in scientific research to study dynamic processes that occur over very short timescales, typically on the order of picoseconds to milliseconds. These techniques involve measuring changes in physical or chemical properties of a system as a function of time to gain insight into the mechanisms and dynamics of processes such as chemical reactions, molecular vibrations, protein folding, and electron transfer reactions. Some common time-resolved techniques include time-resolved spectroscopy, time-resolved X-ray diffraction, time-resolved fluorescence, and time-resolved electron microscopy. These techniques provide researchers with a detailed understanding of the temporal evolution of a system under study and can help unravel complex intermolecular interactions, structural changes, and chemical kinetics. Time-resolved techniques are widely used in various fields such as chemistry, physics, biology, and materials science to investigate fast processes that are otherwise inaccessible using conventional methods.
