Research

The common theme of our research is to investigate size-dependent properties of molecular, ionic, and metal clusters. Experimental methods we use include molecular beam techniques and state-of-the-art laser spectroscopy. We also use theoretical methods to understand and predict the change in atomic and molecular properties as a function of cluster size.

Solvated Ions.The solvation/hydration of atomic and molecular ions has been studied by a variety of methods for over a century; advances from our laboratory now allow us to characterize these processes at the microscopic level. Vibrational spectroscopy of size-selected cluster ions in the gas phase can elucidate the competition between ion–solvent electrostatic interactions and solvent–solvent interactions—in particular, hydrogen bonding. While these studies are of fundamental importance to chemical physics and physical chemistry, knowledge gained from these experiments can be directly applied to a wide and diverse range of problems in chemical biology, materials and atmospheric chemistry.

Infrared Spectroscopy. We have studied the infrared spectra of a number of hydrogen-bonded and van der Waals complexes via vibrational predissociation spectroscopy. Our laboratory performed the first investigation of a homomolecular trimer [(HF)3], detailing the structure, intra- and intermolecular vibrational properties, and predissociation dynamics. Current efforts are directed toward developing new size-selective methods for both larger and metal-bearing clusters.

Theoretical Studies. In support of our experimental investigations, we use a variety of computational and modeling tools. These include ab initio, Monte Carlo and molecular dynamics methods as applied to the study of clusters involving from three to as many as thirty molecular units.
