Abstract

Raman spectroscopy is a useful probe of molecular structures and interactions. Until recently applications to surface layers and thin films was limited by a lack of sensitivity or the need to use enhancement effects which often lead to ambiguities in the interpertation of the resulting spectra. Advancing detector technology and sampling techniques are beginning to change this situation. Preliminary studies on Langmuir - Blodgett films have demonstrated the possiblity of obtaining conventional, or unenhanced, Raman spectra from a single monolayer. Use of waveguide sampling techniques can improve detection sensitivity and polarization measurements even further. Development of CCD and OMA types of array detectors used in these experiments will be discussed. Applications to surface phenomena such as: adhesion, corrosion, tribology, electrochemistry, catalysis, the structure of optically nonlinear films, and surface chemical modification are but a few of the technologically impacted areas.
