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 …
WebNov 9, 2024 · At first glance, the IR spectra look very complicated, but the only three things you need to know are: regions of the spectrum, one number (1500), and location and shape of the peaks. Let’ s considers all of these. IR spectra can be divided into two main regions: Diagnostic region – generally has fewer peaks and provides the clearest information. WebThe infra-red spectrum for a primary amine. 1-aminobutane. Primary amines contain the -NH 2 group, and so have N-H bonds. These absorb somewhere between 3100 and 3500 cm-1. That double trough (typical of primary amines) can be seen clearly on the spectrum to the left of the C-H absorptions.
