REFERENCE RAMAN SPECTRAL DATABASE OF COMMERCIAL PESTICIDES

Abstract

Among several techniques used to study pesticides, Raman spectroscopy stands out for providing fast and reliable results. The objective of this work is to construct a database with Raman spectra of the main commercial pesticides currently used and make it available to the scientific community. With this aim, liquid and solid samples from 78 pesticides were collected. For the Raman spectroscopy analysis of pesticides, a portable Delta Nu Raman spectrometer with a 785 nm laser wavelength and 8 cm^-1 resolution was used. The results obtained from the different pesticides were grouped into tables showing the action class, chemical class, active ingredient, and relative intensities of the characteristic Raman bands.
