        abstract = {Fourier Transform Infrared (FTIR) spectroscopy, which is used to examine molecule rotations and vibrations. Through the simultaneous measurement of infrared light absorption over a broad frequency range, it generates distinct spectral fingerprints for various substances. Molecular structures, functional groups, and molecular interactions in solids, liquids, and gases can all be quickly and nondestructively analysed with this method. A broadspectrum infrared beam is passed through a sample using a Michelson interferometer in an FTIR spectrometer, which simultaneously gathers data on all frequencies. An absorption spectrum that offers a distinct molecular "fingerprint" of the sample is then produced by a Fourier transformation of the resultant signal, or interferogram. Advanced techniques like ATR- FTIR enhance its applicability for surface thin layer analysis. FTIR extensively used in pharmaceuticals, polymers, food, environmental science.},
