Developments in Spectroscopic Investigation of Intermolecular Interactions and Dynamics of Molecular Clusters (#438)

Molecular clusters are collections of two to tens of molecules which are held together by intermolecular forces rather than chemical bonds. When formed under controlled conditions in the gas phase, molecular clusters serve as model systems in which to study certain aspects of solvation in exquisite detail, allowing precise probes of their geometric as well as electronic structures. Spectroscopic data then serves as a starting point for studies of their chemical dynamics, their reactivity, and their thermodynamic properties. This symposium will have as its primary theme the intra- and intermolecular interactions and dynamics of molecular clusters in the electronic excited states and ionic states. The topics to be covered include photoinduced reactive processes such as proton/charge transfer, water migration, and isomerization as well as noncovalent and metal-ligand interactions in solvated and biomolecular clusters. A particular focus will be put on new ways to prepare large clusters and to control their temperature and internal energies, and on innovative techniques for frequency-resolved and time-resolved spectroscopy. The synergy between theory and experiment will also be highlighted, including recent developments in the description of complex potential energy surfaces associated with solvation and photoreactive processes.
