Book excerpt: Analytical Methods for Pesticides and Plant Growth Regulators, Volume IX: Spectroscopic Methods of Analysis covers the progress in spectroscopic methods for pesticide analysis. The book discusses the use of high-pressure liquid chromatography coupled to mass spectrometry for the analysis of heat-labile compounds; and the applications of nuclear magnetic resonance spectroscopy and related techniques, and visible and ultraviolet spectrophotometry. The text also describes the applications of spectrophotofluorometry, infrared spectrometry, and a collection of infrared spectra of important pesticides. Toxicologists, chemists, and people working in pesticide laboratories will find the book invaluable.
