The book introduces the most widely used steady-state and time-resolved spectroscopic techniques, makes comparisions between them, and provides the methodology for estimating the most important characteristics of the techniques such as sensitivity and time resolution. Recent developments in lasers, optics and electronics has had a significant impact on modern optical spectroscopic methods and instrumentations.
