The obtained product was then analyzed by FT-IR spectrum. According to the FT-IR results presented in Fig. 1, CA has a strong stretching vibration peak of –OH at 950 cm−1 (Chen et al., 2020), however, the vibration of –OH significantly decreases in the spectrum of the synthesized...

The FTIR spectrum of the HCP-AA is represented in Fig.4. The peak, having medium intensity is shown at 1590 cm−1that may indicates the presence of the N–H bond. The peak, having medium intensity which is observe at 1508 cm−1, indicates the presence of the C=C bond stretching ...
To confirm that the reduction products be derived from CO2, the photoreduction of13C-labeled CO2was conducted over the IL/Co-bCN. The dominant peak of13CO (m/z = 29) and a small peak of13CH4(m/z = 17) were observed in the selective ion detection chromatography spectrum (Fig....
Warming causes some peak positions and profiles in the spectrum of a H2O/CO2=5 mixture to take on the appearance of pure CO2. Absolute strengths for absorptions of CO2 in solid H2O are estimated. Similar results are observed for CO2 in solid CH3OH. Since the CO2 ( 2 ν 3 ) overtone ...
