Figure 5 shows the FTIR spectra of graphite powder, graphite oxide, and the rGO-TiO2 composite. While no significant peaks were observed in raw graphite, graphite oxide was found to exhibit several characteristic absorption bands of oxygen-containing groups (Figure 5, spectrum b).

Fourier transform infrared (FTIR) spectra were obtained with a Shimadzu spectrophotometer, over a scan range of 500–4000 cm − 1 with an average 16 scans. A background spectrum was obtained for each experimental condition to eliminate the effect of carbon dioxide. 0.2 mg of SOA was weighed and transferred into a mortar, where it was triturated with 250 mg of dry potassium bromide. Fourier Transform Infrared (FTIR) Reference Spectra The Clean Air Act Amendments (CAAA) was published in November 1990. Title III of the Clean Air Act includes a list of 189 hazardous air pollutants (HAPS) for which test methods must be established. But for the purists, an FT-IR is a method of obtaining infrared spectra by first collecting an interferogram of a sample signal using an interferometer, and then performing a Fourier Transform (FT) on the interferogram to obtain the spectrum.

An FT-IR spectrometer collects and digitizes the interferogram, performs the FT function, and displays The background spectrum will contain information about the species of gases and solvent molecules, which may then be subtracted away from our sample spectrum in order to gain information about just the sample. Figure \(\PageIndex{6}\) shows an example of an FTIR background spectrum.
