Abstract
Photoacoustic infrared spectroscopy has been used to study the interactions of a carbamate insecticide with a clay carrier. The ability of photoacoustic infrared spectroscopy to measure infrared spectra from opaque samples non-destructively, is particularly valuable in this study where weak bonds might be destroyed by sample grinding. The results of this study show that the strong N-H stretching modes, which appear at approximately 3300 cm-1 in in the pure insecticide, are missing in the subtraction of the N-H group spectrum. This suggests that the hydrogen attached to the nitrogen of the carbamate is forming a reasonably strong bond with the hydrated silicate structure of the clay carrier. This interaction may effect the release rate of the pesticide upon application.
