Spectroscopic Studies of Fluid/Solid Interfaces
Abstract
This program of research has been to develop spectrosco pic methods for exploring chemical structure and molecular dynamics at interfaces between dielectric solids and liquids or supercritical fluids. 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 absorbed or bound. Studies focused on the interfacial chemistry of silica and derivatized silica surfaces in contact with liquids and dense gases. The spectral response of probe molecules was used to observe differences in the chemical environment at the liquid-solid interface due to the presence of bound or adsorbed molecules.
