FIGURE 2: Diffuse reflectance FTIR spectra of alkyl–amide packing (solid line) and starting silica (dashed line). on a 5-m dp, 80-Å, 180-m2/g Zorbax Rx-Sil silica support (Hewlett-Packard) by proprietary processes. The carbon values for this column packing typically were 10% for...
For LB electrolytes, the FTIR bands at 1670 cm−1 assigned to C = O of BL and 747 cm−1 assigned to TFSI− shift to 1657 and 739 cm−1, respectively, after solution formation (Fig. 1a), which resulting from the strong coordination interaction between Li+ and C = O ...
The water-soluble hyperbranched unsaturated poly(amide-ester)(HBP) was modificated by the reaction of double bond with styrene and the system can be self-emulsionized.The result of FTIR analysis showed that expected products were gained.The effects of temperature,reactant ratio,stirring velocity and...
Different from PUMHS, there is still one strong H-bond donor NH but two strong possible acceptors C=O and ether O in PUMSS (bottom of Fig.1). Fig. 2 shows their obvious differences in FTIR spectra in both νNH and νC=O bands. First, the peak of ...

Polymer characterization The structure of the polymers was identified by FTIR spectroscopy. The typical FTIR spectra of the PIs are presented in Figure 2 for PI-III and PI-I. In the FTIR spectra, the structure of the synthesized PIs was confirmed by the disappearance of the anhydride C¼O ...
Amino acid side chain contribution to protein FTIR spectra: impact on secondary structure evaluation Prediction of protein secondary structure from FTIR spectra usually relies on the absorbance in the amide I–amide II region of the spectrum. It assumes th... JD Meutter,E Goormaghtigh - 《Europ...
It is well accepted that vNH and vC=O bands in FTIR are the two typical bands used to judge if the H-bonds have been formed in PU. Their frequencies are usually used to analyze the H-bond strength. Both νNH and νC=O bands will shift to lower frequency when H-bond (NH…O=C)...
The properties of N -methylacetamide (NMA) molecules encapsulated in the reverse micelles (RMs) formed by anionic surfactant aerosol OT (AOT), are studied with vibrational spectroscopy and computation. Vibrational spectra of the amide I′ mode of the ful
