Infrared Spectroscopy (IR): The term "infra-red" covers the range of the electromagnetic spectrum between 0.78 and 1000 mm. If the molecule is not too large or complex, the determination should be very accurate. It is a simple and reliable technique for measurement, quality control and dynamic measurement. Underlying principal of infrared spectroscopy is based upon the molecular vibration which is further composed of the stretching and the bending vibration of a molecule. 1] It relies on inelastic scattering, or Raman scattering, of monochromatic light, usually from a laser in the visible, near infrared, or near ultraviolet range. It is based in the fact that molecules absorb specific frequencies that are characteristic of their structure. endstream endobj startxref Complete classes of compounds can be rapidly excluded during the interpretation by the use of no-band information. The use of infrared spectroscopy began in the 1950's by Wilbur Kaye. A primary goal of this book has been to fully integrate the use of both IR and Raman In IR spectroscopy, the vibrational transitions are induced by absorption of light quanta from a continuous light source in the IR spectral region.
