WebIR cameras have detectors that absorb a narrow band of infrared radiation in the electromagnetic spectrum and transform it into a 2-dimensional temperature field. The wavelength emitted is given by Wein’s displacement law, as described for instance by [19]. The main advantages of using IR cameras are their quick response time and high … WebSince most organic compounds have C-H bonds, a useful rule is that absorption in the 2850 to 3000 cm-1 is due to sp 3 C-H stretching; whereas, absorption above 3000 cm-1 is from …
