WebMethods of Measuring Oil Chemistry INFRARED SPECTROSCOPY. Infrared spectroscopy uses a radiative source, a detector, and a computer to study the interaction of matter and light. Oxidation and nitration products appear as peaks in the IR spectrum between 1600 and 1800 cm-1. Sulfation products appear as peaks in the IR spectrum around 1120-1180 cm-1.
