Principles of FTIR Spectroscopy In FTIR analyses, Infrared light from the light source passes through a Michelson interferometer along the optical path. The Michelson interferometer comprises a beam splitter, moving mirror, and fixed mirror. The light beam split into two by the beam splitter is reflected from the movin FTIR Spectroscopy (Fourier Transform Infrared) FT instrumentation. Now let's look at an FT instrument. We still have a source, a sample and a detector, but everything else is different. Now, we send all the source energy through an interferometer and onto the sample. In every scan, all source radiation gets to the sample A) 1.)Infrared (IR) spectroscopy: based on IR absorption by molecules as undergo vibrational and rotational transitions. Absorption of radiation in this region by a typical organic molecule results in the excitation of vibrational, rotational and bending modes, while the molecule itself remains in its electronic ground state The FTIR instrument relies upon interferences of various frequencies of light to produce a spectrum. It has a source, sample, two mirrors, a laser reference, and detector, but the assembly of components also include a beamsplitter and the two strategic mirrors that function as an interferometer

Fourier-transform infrared spectroscopy (or FTIR, for short) is a method of exploring the physical properties of solids, liquids, and gases. More specifically, it allows the study of the absorptive and emissive properties of materials Principle of Infrared (IR) Spectroscopy. Infrared Spectroscopy is the analysis of infrared light interacting with a molecule. The portion of the infrared region most useful for analysis of organic compounds have a wavelength range from 2,500 to 16,000 nm, with a corresponding frequency range from 1.9*1013 to 1.2*1014 Hz

IR stands for 'Infrared' which ranges from 2.5µm to 15µm in the electromagnetic spectrum. FTIR on the other hand is a spectroscopic technique. Fourier Transform Infrared spectroscopy is used to determine the functional group in any given organic s.. Fourier transform infrared (FTIR) spectroscopy probes the vibrational properties of amino acids and cofactors, which are sensitive to minute structural changes inherent advantages of FTIR over conventional IR instrumentation, including simpler instrumentation, faster spectral acquisition, and spectral data manipulation capabilities, all which led to its rapid development.

FTIR Imaging is a complimentary Imaging tool and is a very versatile analytical technique for spectrochemical imaging. The advantage of chemical imaging compared to other sensor technologies is the ability to analyze the spatial distribution of the component materials in blends, granules or finished dosage forms The FTIR spectra of most fats and oils appeared almost visually similar; the slight differences in the spectral features reflect the variations in the fatty acid composition (Figure1 to 6). Every peak in the spectra represents structural and functional group, either of the oil or other minor components Raman instrumentation was developed (based around arc lamps and photographic plates) and soon became very popular up until the 1950s. Since these early days, Raman instrumentation has evolved markedly. Modern instrumentation typically consists of a laser, Rayleigh filter, a few lenses, a spectrograph and a detector (typically a CCD or ICCD) The term Fourier Transform Infrared Spectroscopy (FTIR) refers to a development in the manner in which the data is collected and converted from an interference pattern to a spectrum. It is a powerful tool for identifying types of chemical bonds in a molecule by producing an infrared absorption spectrum that is like a molecular fingerprint

All three techniques have various advantages and disadvantages with respect to instrumentation, sample handling, and applications In this study, the reflectance-FT-IR (r-FT-IR) spectroscopy is demonstrated to be a suitable option for non-invasive identification of textile fibers. A collection of known textile fibers, 61 single-component textiles from 16 different types, were analyzed, resulting in more than 4000 individual spectra. The r-FT-IR method was compared with ATR-FT-IR spectroscopy using two instrumental. A CCD (Charge Coupled Device) is a silicon-based multichannel array detector of UV, visible and near-infra light.
