    abstract = "The Raman spectrum of the organophosphorus pesticide fenthion is
presented, and a novel Fourier transform (FT)-Raman method for the
quantitative determination of fenthion in pesticide formulations is
proposed. Calibration curves based on Raman intensity and band area at
2951, 1065, 661, and 601 cm(-1) were linear (correlation coefficients:
0.991-0.998) in the concentration range of 0.4-4.36 M. Detection limits
ranged between 0.14 to 0.36 M and precision from 0.4 to 6.8% relative
standard deviation (RSD) (n = 4), Spectra normalization against the 802
cm(-1) cyclohexane band proved to be effective in minimizing the effect
of excitation intensity fluctuations and sample positioning changes in
calibration data, resulting in improved long-term stability of the
calibration curves. Results obtained during the analysis of the Lebaycid
formulation compare well with those obtained by the gas chromatography
(GC) reference method. The proposed FT-Raman method Is fast, simple, and
safe, avoids sample pretreatment, and minimizes handling of toxic
samples."
