Molecular Spectroscopy as a Probe of Quantum Solvation — •R. E. Miller — Department of Chemistry, University of North Carolina, Chapel Hill NC 27599
Helium nanodroplets are being used to study quantum mechanical exchange in a finite system. These dynamical processes are probed by doping the droplets with a molecule, the spectroscopy of which is sensitive to the quantum solvent environment. Infrared laser spectroscopy is found to be an ideal method for probing the associated dynamics, providing detailed information on the rotational and vibrational motion of the solvated molecules and the nature of the coupling of these to the solvent. These nanodroplets also provide us with a unique method for forming clusters and nanoparticles with unique structures, resulting from the low temperature growth. A number of applications of this type will be discussed.
