The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. There are two tables grouped by frequency range and compound class. 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). The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance ) on the vertical axis vs. frequency or wavelength on the horizontal axis.

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. Figure \(\PageIndex{6}\). Background IR spectrum FTIR Spectrometers Featuring improvements in interferometer and detector design, the IRTracer-100 offers high sensitivity. This sensitivity combined with the LabSolutions IR Contaminant Analysis Macro enables easier, quicker and more accurate analysis of small samples.
