Editing Time-resolved spectroscopy (section)

{{Short description|Spectroscopic technique}}
In [[physics]] and [[physical chemistry]], '''time-resolved spectroscopy''' is the study of dynamic processes in [[material]]s or [[chemical compound]]s by means of [[spectroscopy|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 [[Material properties (thermodynamics)|properties of a material]]. With the help of pulsed [[laser]]s, it is possible to study processes that occur on time scales as short as 10<sup>−16</sup> seconds. This is done to overcome the hampering background interference that often disrupts and challenges Raman measurements to improve spectra quality. All time-resolved spectra are suitable to be analyzed using the two-dimensional correlation method for a correlation map between the peaks.<ref name=Noda_2D_correlation/>
