ABSTRACT
Recent innovation of the ultrafast lasers makes it possible to investigate a variety of dynamics of molecules with very high time resolution. Femtosecond and picosecond time-resolved spectroscopy enables us to investigate ultrafast events including the electronic relaxation, vibrational relaxation, energy transfer, electron transfer, as well as the structure and properties of short-lived transients such as excited states. Although ultrafast spectroscopy has been mainly conducted for homogeneous systems so far, the combination with microscopic techniques is indispensable when we study inhomogeneous systems. Because the interaction between molecules and local environments causes significant changes in dynamical properties
