WebWhat is FTIR? Fourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties. ... The intensity of the absorbance ... WebMar 18, 2015 · The absorption intensity of a spectral transition (the area under the absorption curve - usually it correlates with the peak height) is given by the same equation except that rather than use the molecular dipole moment $\mu$, one uses what is called the transition dipole moment. Rather than consider the ground state distribution of …
WebIn FTIR, a fast Fourier transform (FFT) is used to convert interferograms to power spectra so the numbers of data points for each resolution are all powers of two. (See Table 2.) As can be seen from the figure, the light …
