In continuation of their efforts on laser spectroscopy probing of               excitation and coherence processes, they propose to use this                    renewal grant to undertake research in the following areas:  (a)                ultrashort time dynamics of electron and excitation transfer in                 model systems in condensed media; (b) selective-pulse excitation                for the invesitgation of coherence and relaxation processes; and                (c) laser spectroscopy studies of microscopic solvation and                     clustering.  The techniques that they shall use in this research                (which are already used in their laboratory) are picosecond and                 femtosecond spectroscopy, multiple pulse optical excitation                     methods, and multiphoton (TOF and PES) detection methods.  Their                objectives are to apply (and modify) these techniques to learn                  about the dynamics of energy relaxation, solvation, and coherence               in condensed media, and to examine the picosecond and femtosecond               dynamics of molecules undergoing (microscopic) solvation and                    clustering formation.
