The direct study of lifetimes of various molecular vibronic states within an electronic manifold is shown to have produced much new data about the dynamics in the photoexcited states in the short decade of its existence. It is demonstrated that it is now possible, with the use of modern high resolution tunable lasers, to obtain lifetimes with a resolution comparable to high resolution absorptivity measurements. This directly yields dynamic information about the photoexcited state. In this way one has the possibility of obtaining highly precise spectroscopic information with respect to “lateral” transitions, such as Franck-Condon factors, vibrational induction effects, etc.
