Excited Resonance

The feasibility of resonance Raman spectroscopy in the detection of hazardous chemicals in water has been tested on some nitrophenol-based pesticides and fungicides. In most cases, detection limits below the parts per million level were obtained. The method was also tested on an artifically polluted river water sample.

Krf Excimer Laser

The feasibility of quantitative resonance Raman spectroscopy with a KrF excimer laser providing primary radiation at 249 nm has been examined. The instrumentation is described, and results are reported for measurements with a photomultiplier detector and scanning monochromator. Considerations affecting the success of the internal standardization are described. A least-squares fitting procedure is employed for quantifying the overlapped analyte and internal standard spectral lines. Instrumental detection limits of 2.2, 1.2, and 1.0 mg/L are reported for anthracene, 9-methylanthracene, and 2-methylanthracene, respectively, for spectra obtained with 120 laser pulses per step. Detection limits in the low ppb range are projected for a system employing an intensified diode array detector.
