Uses :The Laser Flash Photolysis technique provides the direct observation of the excited state absorption characteristics to be studied as a function of time (transient absorption) and wavelength for a sample that has been optically stimulated by pulsed laser. In order to generate a sufficiently high concentration of excited state species, a powerful excitation source in required, as a laser Q-Switched Nd :YAG. It can also provide radiative and non-radiative singlet and triplet lifetimes .
