CB has many reflectance spectra depending on the angle of light falling on the background and the angle of illumination of the digital camera/hyperspectral camera (Sönke, 2016). Advancement phase 3, exponential relationships of multidimensional CBs-DGTWSICB in UV–Vis-IR spectrums Figures 7, ...
Again, spectral subtraction was performed between the spectra of the fibers extracted from the composites with and without coupling agent. The results agree with the observations made on the bulk composites, that is, the absence of the carbonyl/carboxyl band and the presence of amide and/or ...

(see Table2). Samples 3.2 and 5.2 were reliably identified as silk, thanks to the characteristic spectra. The cellulose-based fibers in samples 3.1 and 5.1 were found to be cotton and viscose, respectively. Optical microscopy was needed for these two samples as a confirmatory method because ...

IR spectra have traditionally been interpreted by assigning absorptions that fall in particular frequency ranges to specific functional groups within molecules, in what is termed the functional group approach to spectral interpretation. Thus, absorption bands in the range 2800–3050 cm−1 are attribute...
