Their structural framework consists of a C=O group and two C-O bonds. This gives rise to three intense peaks called the Rule of Three with peak positions at approximately 1700, 1200, and 1100 wavenumbers.
WebMar 24, 2024 · The ratio of the band intensities in the FTIR spectra of the PGA-Ca mixtures were related to the ones in the FTIR spectra of PGA (e.g., C=O/C–O–C ratio of the PGA-Ca mixture divided by the C=O/C–O–C ratio of PGA) to determine the relative changes (band ratios). The spectral data (relative band shift as well as band ratios) were tested ... WebFourier-transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the radiation, electromagnetic or not. It can be applied to a variety of types of spectroscopy including optical spectroscopy, infrared spectroscopy …
