Abstract:

This program of research was to develop spectroscopic and kinetic methods for exploring chemical structure and molecular dynamics at interfaces between dielectric solids and liquids. The research was carried out using fluorescence and vibrational spectroscopy from probe molecules where spectral and temporal differences in emission, absorption, or scattering provide information about the surface onto which they are adsorbed or bound. Studies focused on the interfacial chemistry of insulating surfaces in contact with liquids. The spectral and temporal response of bound or adsorbed molecules were used to observe differences in the chemical environment at the liquid-solid interface. Time-resolution was also valuable in sorting out heterogeneous surface environments from differences in emission rate constants, adsorption rates, and reaction kinetics.
