In physics and physical chemistry, time-resolved spectroscopy is the study of dynamic processes in materials or chemical compounds by means of spectroscopic techniques. Most often, processes are studied after the illumination of a material occurs, but in principle, the technique can be applied to any process that leads to a change in properties of a material. With the help of pulsed lasers, it is possible to study processes that occur on time scales as short as 10 seconds. All time-resolved … WebThe time-gated emission spectra (200-µs data collection following a 100-µs postexcitation delay) of 125 nM intact or BACE-cleaved peptides are shown in Figure 3.These spectra show emission from both the donor and the acceptor, as mea-sured on a Tecan Safire 2™ microplate reader.
