The applications of infrared spectroscopy to pharmaceutical sciences is small compared to the applications of infrared spectroscopy to the fields of chemistry, biology, and biochemistry. It is used to detect different functional groups in PHB. Fourier transform infrared (FTIR) spectroscopy probes the vibrational properties of amino acids and cofactors, which are sensitive to minute structural changes. PDF | On Jun 13, 2020, Susheel Gulati published FOURIER TRANSFORM INFRARED SPECTROSCOPY | Find, read and cite all the research you need on ResearchGate Time to compute Fourier transform reduced from days to minutes Over the last 50 years FTS have moved from the specialized domain of the physics laboratory and are now found as standard diagnostic tools in many branches of science and industry. However, with the development of Fourier transform infrared (FTIR) spectroscopy, it has become a more popular method for the quantitative analysis of complex mixtures, as well as the investigation of surface and interfacial phenomena. This book explains difficult theoretical concepts using diagrams and easy-to-understand language with a minimum of complex mathematics. ), pp. Figure 3. 185–196, Fourier transform spectroscopy. The lack of specificity of this technique, on the one hand, permits us to probe directly the vibrational properties of almost all the cofactors, amino acid side chains, and of water molecules.
