WebFigure 2. Group frequency and fingerprint regions of the mid-infrared spectrum. The region of the infrared spectrum from 1200 to 700 cm -1 is called the fingerprint region. This region is notable for the large number of infrared bands that are found there. Many different vibrations, including C-O, C-C and C-N single bond stretches, C-H bending ...

WebGeneral Assignment of the PTFE-TFM Polymer Spectrum Infrared (ATR) and Raman spectra of the PTFE-TFM wall sample after 200 digestion cycles are shown in Figure 2. The proposed assignments (Table I) were made on the basis of the general formula of PTFE: –[–CF 2 –CF 2–] n–. Dominant IR bands at 1299, 1199, 1146, 715–774, WebThe FTIR transmittance spectra of samples A and B are shown in Fig. 3 and the assignment of the bands is shown in Table 3. The characteristic bands almost at 1085, 800 and 460 cm-1 are correspond to the stretching, bending and out of plane of Si-O bonds, respectively.

The FTIR of the ARS matched with these band assignments relatively well (Table 3, Figure 6). After ARS sorption from a single solution, most of the bands remained at the same location, and they were barely visible due to the low ARS sorption (up to 45 mmol/kg, or 14 mg/g). nature before and after drawing
