Direct Analysis of Organic Pollutants in Complex Samples by Resonance Raman Spectroscopy

A rationale for selecting resonance enhanced Raman spectroscopy as the basis for design of a method of chemical analysis for direct application to marine samples is presented. Major points are the high information content of vibrational spectra, the wide dynamic range of Raman measurements, and its ability to produce spectra which are linear combinations of componets that originate in various sample constituents. The use of an injection-locked excimer laser, together with integrated data processing to solve various problems, is discussed.
