What is an infrared spectrophotometer?
Infrared spectrophotometer is a device used in organic chemistry to collect information on the structural properties of organic molecules and compounds. In this particular type of spectrophotometer, infrared light is absorbed by chemical compounds and the movement of chemical bonds is analyzed. Infrared spectrophotometers can be used to identify unknown chemicals and to determine the cleanliness of the sample. They are often used in research applications for industry and chemical processes. Infrared light falls between visible light and microwave radiation on electromagnetic radiation. This type of light can be further divided into close, medium and far IR ranges, while the mean IR range is the most useful in infrared spectroscopy. Light in this area may have a wavelength or λ 3x10 -4 to 3x10 -3
Organic molecules can absorb the infractionAlthough light and as a result they can vibrate in different ways. The absorption of infrared light occurs whenever the radiant energy of the light itself coincides with the energy of the molecular vibration. Movement can be described by symmetrical and asymmetrical stretching of molecular bonds and bending of molecular bonds.
Infrared spectrophotometer, which uses a prism or grid to distribute the source of infrared radiation into separate frequencies, is called dispersion infrared spectrophotometer. More modern design, Fourier transformation infrared spectrophotometer, is the preferred device in research and industrial environment. The accuracy of the reported waves is constant throughout the ICE devices due to constant strength resolution.
Infrared spectrophotometer Fourier transformation consists of five basic parts - sources of infrared radiation, interferometer, sample, detector and computer. InferAlthough the radiation source is usually a glowing source of the black body and the amount of emitted energy is controlled by aperture. Interferometer is an optical device that performs spectral coding on infrared radiation. The beam passes through the sample and then a detector that decodes the interferogram signals from the interferometer. The last step is a computer that performs Fourier's data transformation and represents it in a usable interface.
Infrared spectrophotometer is unique in that it can be used to identify functional groups in an unknown sample. Some function groups have "fingerprints" or a unique absorbent peak that can be identified from the output graph of the infrared spectrofotometer. The weight and database of organic chemical values can be used to identify unknown organic samples.
