![]() ![]() The Fingerprint Region The fingerprint region is the region to the right-hand side of the diagram (from about 1500 to 500 cm-1) usually contains a very complicated series of absorptions.IR spectroscopy is useful for finding out what kinds of bonds are present in a molecule, and knowing what kinds of bonds are present is a good start towards knowing what the structure could be. The wavelengths found in infrared radiation are a little longer than those found in visible light. Interpreting Infrared Spectra This chapter will focus on infrared (IR) spectroscopy.Chemical compounds have different chemical properties due to the presence of different functional groups. Infrared Spectroscopy Infrared (IR) spectroscopy is one of the most common and widely used spectroscopic techniques employed mainly by inorganic and organic chemists due to its usefulness in determining structures of compounds and identifying them.The fundamental measurement obtained in infrared spectroscopy is an infrared spectrum, which is a plot of measured infrared intensity versus wavelength (or frequency) of light. Infrared: Interpretation Infrared spectroscopy is the study of the interaction of infrared light with matter.Infrared: Application Infrared spectroscopy, an analytical technique that takes advantage of the vibrational transitions of a molecule, has been of great significance to scientific researchers in many fields such as protein characterization, nanoscale semiconductor analysis and space exploration.Identifying the Presence of Particular Groups This page explains how to use an infra-red spectrum to identify the presence of a few simple bonds in organic compounds.In addition, since FTIR spectrometers can be hyphenated to chromatography, the mechanism of chemical reactions and the detection of unstable substances can be investigated with such instruments. How an FTIR Spectrometer Operates FTIR spectrometers (Fourier Transform Infrared Spectrometer) are widely used in organic synthesis, polymer science, petrochemical engineering, pharmaceutical industry and food analysis. ![]()
