Research Interests

We are studying the structure of electronic excited states of small molecules in the gas phase using a nitrogen-pumped dye laser. We are using the double resonance technique where we first pump the molecule to a low-lying excited state with the dye laser; we then excite to higher lying states with a small portion of the initial nitrogen pulse. Presently we are probing the vibrational levels of ion-pair states and using Franck-Condon calculations to assign the various transitions we observe. In the future we would like to study molecular Rydberg states in which the electronic structure of a molecule mimics that of a hydrogenic (single-electron) atom. We have also begun to study weak intermolecular attractive forces in small, organic molecules that give rise to short-range ordering and cluster formation in the solid state.
