This applications note compares the sensitivity of a single-reflection ATR to multiple-reflection ATR for the nitrile functional group infrared transition.

Single reflection ATR spectroscopy is valuable for examining thermally induced changes in materials. Changes in the water concentration and amide bands of egg yolk were observed using the Harrick DiaMaxATR accessory. Further analysis is possible to obtain more rigorous identification of the heat-induced structural changes.

Monolayers and other thin coatings on Si and other high refractive index substrates are of key importance in materials science, bioscience, synthetic organic, and semiconductor research.
