Fourier Transform Infrared Spectroscopy (FTIR) is an effective analytical technique for quickly identifying the “chemical family” of a substance. Typically, organic and polymeric compounds (and, to a lesser degree, inorganic compounds) produce a “fingerprint” IR spectrum, which can be compared to...
With FTIR testing, the light is measured using an infrared spectrometer which produces the output of an infrared spectrum. The FTIR spectrum is displayed as a chart. The vertical axis shows how much infrared light the substance absorbs. The horizontal axis represents the frequency, or wavelength, ...

The electromagnetic spectrum consists of different regions corresponding to different energy (E), frequency (ѵ), and wavelength (λ) ranges as seen in Figure 2. The unit for near-, mid-, and far-infrared, the wavenumber (cm-1), is derived from the inverse relationship between wavelength ...

From all mentioned above it is made clear that exogenous citric acid could really ameliorate distinctly the effect of aluminum on soybean roots which was detected by direct determination of FTIR spectrum, giving the fact that FTIR could reflect the ameliorating effect of exogenous organic acid on ...
Re: FTIR charts, what`s the material? « Reply #3 on: November 02, 2018, 05:44:25 AM » You didn't say anything about fiberglass or fire retardant!I think the first one is Nylon 6,6. (Google "Nylon 66 IR spectrum".) I'm not sure about the second, but 2299 suggests an ...
Point out the low and high energy ends of the electromagnetic spectrum, from long wavelengths of light at 10^-5 cm-1 (radio waves) to 10^9 cm-1 (x-ray energy). Note from our chart that a molecule behaves differently when exposed to these different energy levels. For example when ...
