Paper Abstract

Raman scattering techniques, because of the vibrational information they contain, have numerous applications in the measurement and identification of aqueous pollutants in groundwater, as well as other contaminated waters. However, the extension of Raman techniques using fiber optics to remote sensing of groundwater is not completely straightforward. Single-fiber optrodes provide the greatest signals but also large background levels. Multiple-fiber optrodes offer lower background levels but are not practical over very long distances and are not as sensitive as single-fiber optrodes. The difficulties of obtaining Raman spectra with fiber optics are discussed, and the potential techniques for overcoming the limitations of single-fiber devices are descrivbed. The results of Raman spectral measurements that were made using a dual-fiber optrode in a novel forward-scattering configuration will be presented. The possible extension of these results to surface-enhanced Raman (SER) scattering will be discussed. In addition initial results of SERS performed with optical fibers will be presented, along with a description of future directions for this research.
