WebJun 1, 2024 · IR spectroscopy is a useful analytical technique for both qualitative and quantitative analysis and it is based on molecular vibrational transitions. Powders, films, liquids, solutions, pastes, fibres, gases and surfaces can all be examined with IR technique. It is a useful tool to identify functional groups in organic and inorganic compounds. WebWhat is FTIR? FTIR 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.
