The films exhibit the typical absorption peaks related to Hf–O bonds. Interestingly, a trend is clearly observed between the transmittance, crystallographic planes and FTIR characteristic peaks as deposition temperature increases. Moreover, the fabrication and characterization of MOS capacitors is ...
3.5. Bioactivity of spectral characteristic and representing functional groups Figure 4 illustrates the line loading plot obtained from multivariate data analysis of the extracts of P. macrocarpa. This plot can make the recognition of the possible biological activity of peaks from the FTIR spectrum easi...

and OH-stretching band (characteristic for water)41. The critical intrinsic contact angle is measured on a flat, FDTS-coated crystal using premixed IPA-water mixtures with the same critical composition that leads to spontaneous wetting in the ATR-FTIR experiments. Figure5and Table2summarize the e...
There is no periodic arrangement of atoms and molecules in amorphous materials. However, according to the Gaussian distribution, there are still average characteristic distances between the atoms and molecules located in the material. Because of the normal distribution of these distances, the intensity ...
FTIR spectra of: a) Methanol treated pure SF. Three characteristic peaks in 1630 cm−1 (amide I), 1530 cm−1 (amide II), and 1230 cm−1 (amide III) are revealed due to β-shee...

CO hydrogenation on silica supported cobalt catalysts studied by in situ infrared spectroscopy revealed absorption bands characteristic of linearly absorbed CO on metallic cobalt. The constant frequency (2068 (+-) 4 cm(sup -1)) of this band at different reaction conditions (H(sub 2)/CO=2), P...
All samples showed characteristic peaks centered at 3290 cm−1 (assigned to O-H stretching of alcohols or phenols) and at 2930–2860 cm−1 (assigned to C-H stretching of alkynes). The peaks at 1742 cm−1 were associated to C=O, typical in carboxylic acids. The absorption at 1649 ...
Table 2. Assignments of prominent peaks observed in biological IR spectra. Many studies have introduced FTIR as a promising biophysical tool for protein structural characterization and monitoring dynamic conformational changes [91]. The IR spectra of protein molecules exhibit many characteristic vibrational...
