Mid-Infrared (IR) spectroscopy is an extremely reliable and well recognized fingerprinting method. Many substances can be characterized, identified and also quantified. One of the strengths of IR spec-troscopy is its ability as an ana-lytical technique to obtain spectra from a very wide range of solids, liquids and gases. However, in

Fourier Transform Infrared (FTIR) has been developed as a result “absorption versus wavenumber” or The mid-IR spectrum is the most widely used. Despite some differences in FTIR spectra among bacterial strains, experimental conditions, or changes in microbiological parameters, the IR absorption bands
FTIR Spectroscopy works in a wide-range of chemistries in which the molecule is infrared active, the chemistry is in solution or off-gas, and the concentration is

FTIR spectroscopy is a potent tool for the study of soil and soil processes. Since its initial application to study the mineral and organic components of soils in the mid-20th century, this technique offers characterization of minerals, organic matter, and processes such as mineral weathering, reduction–oxidation, and ion and organic compound binding to mineral surfaces. Fourier Transform Infrared Spectroscopy (FTIR analysis or FTIR Spectroscopy) is an analytical technique used to identify organic, polymeric, and in some case
Comparison of Raman and IR Spectroscopy, Raman Spectroscopy, IR Spectroscopy. In a molecule with a center of symmetry it is seen that vibrations that are Raman active are IR inactive and vice-versa, this is called the Principle of mutual exclusion (eg, as in CO2 see details in the end). FTIR and Raman spectroscopy are complimentary techniques. Both are based on molecular vibrations; however Raman focuses on scattering of light, along with the change in polarizability of a molecule… FTIR uses absorption of light, and depends on a change in dipole moment.
Michelson Interferometer The Michelson interferometer, which is the core of FTIR spectrometers, is used to split one beam of light into two so that the paths of the two beams are different. Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas.
