WebHowever, FTIR spectroscopy is a disperse method, which means that measurements are performed over a broad spectrum instead of a narrow band of frequencies. Figure 2.26 shows a schematic of a FTIR spectrometer. A blackbody source emits IR radiation over a range of wavenumbers, typically between 4000 and 400 cm −1 for (fire) gas analysis. … WebThe FTIR spectra for the neat polyester and basalt/woven glass fiber reinforced composites from 4000 to 400 cm −1 wavenumbers are shown in Figure 2. Based on the UP spectrum, some low intensity ...
