WebFeb 3, 2024 · FTIR spectroscopy has become a major tool to determine protein secondary structure. One of the identified obstacle for reaching better predictions is the strong overlap of bands assigned to different secondary structures. Yet, while for instance disordered structures and α-helical structures absorb almost at the same wavenumber, the … WebTable 2 summarizes the FTIR peak area ratios from specific absorbance peaks evaluated from the EVAC spectra. The table shows the peak area ratios of the 1236/1467 cm-1 peaks, the 1020/720 cm-1 ratio, and the 1735/720 cm-1 ratio. In all cases as the % PVAc increases in the EVAC copolymers the ratios also increase.
