WebFourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer, which measures … WebTable 6.1 Characteristic IR Frequencies of Stretching Vibrations. The information in Table 6.1 can be summarized in the diagram for easier identification (Figure 6.3b), in which the IR spectrum is divided into several regions, with the characteristic band of certain groups labelled..
