WebFTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample.

WebOct 9, 2024 · How does Fourier Transform Infrared Spectroscopy (FTIR) work? Light from an FTIR light source is split into two beams by a beam splitter (similar to a half mirror). One beam is transmitted to the moving mirror and the other beam is reflected by the fixed mirror. WebIn modern FTIR spectrometers, this modulated signal is passed through the sample and is then measured by a detector. Herres and Gronholz note "…the wings of the interferogram, which contain most of the useful spectral information, have a very low amplitude. This illustrates the need for ADC's of high dynamic range in FT-IR measurements.

WebRaman spectroscopy is a molecular spectroscopic technique that utilizes the interaction of light with matter to gain insight into a material's make up or characteristics, like FTIR. The information provided by Raman spectroscopy results from a light scattering process, whereas IR spectroscopy relies on absorption of light.
