Polyethylene ftir peak assignments
WebPeak appearing at 720 cm-1 was assigned to CH 2 long chain. Peak appearing at 1092 cm-1 was due to Si-OCH 3. The peak at 1378 cm-1 was treated as an internal reference peak as CH 3 groups were not getting affected in the grafting process. The ratio of absorbance at 1092 cm-1 to the absorbance at 1378 cm WebMay 2, 2016 · As “Bisphenol A” is relatively large molecule and many peaks are very near to each other, so it is hard to assign the individual peaks distinctly without multiple assignments as indicated at the end of Table 1. 5. Conclusion. We have presented FTIR (400–4000 cm −1) spectra of “Bisphenol A.” Peaks (400–4000 cm −1) have been ...
