WebApr 12, 2024 · ABSTRACT. Near-infrared spectroscopy (NIRS), coupled with modeling and chemometrics, has been used to age grade anopheline and aedine mosquitoes; however, NIRS has not been widely used in field studies to assign mosquitoes to age classes. One reason is the relative cost of NIRS spectrometers. We developed a spectrometer system … WebNelson CHEM 3153 1 CHAPTER 2: INFRARED (IR) SPECTROSCOPY IR spectroscopy is a simple and rapid instrumental technique that can give evidence for the presence of various functional groups. IR spectroscopy depends on the interaction of molecules or atoms with electromagnetic radiation. Infrared radiation causes atom and group of atoms of organic …
