Avgaserna analyserades med GC-MS och härdningen studerades med FTIR. Changes in the IR-spectrum could be followed by looking at the hydroxyl peak at

FTIR graph are collectively known as the fingerprint region. Each region is unique for an individual compound and are thus extremely helpful in comparisons between different FTIR graphs. The exact model used in this research was the Perkin Elmer (Model Spectrum Two) for taking spectrum data in the wavelength range of 4000-7000 cm-1.

By using ultra-fast scan mode, the time needed for routine spectral checks can be shortened.

All Rights Reserved. Formula: C6H8O7: InChI The IR Spectrum Table is a chart for use during infrared spectroscopy. 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 signal from the interfering beams of the HeNe is monitored by a detector. What is observed is a sinusoidal signal. Functional Group: Characteristic Absorption(s) (cm-1) Notes: Alkyl C-H Stretch: 2950 - 2850 (m or s) Alkane C-H bonds are fairly ubiquitous and therefore usually less useful in determining structure.
