Sources of continuous radiation A hot material emits a continuum of radiation. In infrared spectroscopy, IR radiation is passed through a sample, Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted). This is the basic principle of UV spectroscopy. What is FT-IR FT-IR stands for Fourier Transform Infra Red, the preferred method of infrared spectroscopy. FTIR Spectroscopy (Fourier Transform Infrared) Infrared spectroscopy is an important technique in organic chemistry. of FTIR Spectroscopy. It measures the frequencies at which the sample absorbs, and also the intensities of these absorptions. spectroscopy Núria Ferrer Unitat d’Anàlisi Molecular, CCiTUB, Universitat de Barcelona.

An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. Fourier transform infrared spectroscopy is preferred over dispersive or filter methods of infrared spectral analysis for several reasons: • It is a non-destructive technique. This radiation is one which is emitted by the substance when the electrons transit from excited state to ground state. [cited 2020 Mar 21]. • It can increase speed, collecting a scan every second.
