What is infrared spectroscopy?
Infrared spectroscopy is a branch of spectroscopy that focuses on the infrared electromagnetic spectrum area. This area of the spectrum is located between the visible spectrum and the microwave. People are often aware of infrared radiation because they can produce heat, so it's something that can be reduced, even if it cannot be seen or heard, but also has a number of other characteristics that are interested in people like chemists. One of the key tools in spectroscopy is a spectrometer, a device that can detect different wavelengths of energy. In the case of infrared spectroscopy, scientists are particularly interested in infrared radiation and use spectrometers that are calibrated to work with this type of radiation.Cher or forensic technician can be confronted with an unknown substance. If you want to learn more about the substance, the sample could be inserted into the spectrometer and subjected to infrared radiation to excite the molecules inside. Some radiations will be absorbed that can be read by spectrialOMETRA, and others not, which can also be detected by the device. The device returns a print that shows how much radiation has been absorbed and which area of the infrared spectrum was connected.
Classically, infrared spectroscopy is the result of a print with a number of peaks in specific points. These peaks can correlate with graphs describing the results of spectroscopy of known substances. The researcher can find out whether there are any substances with similar infrared "signatures" to identify an unknown sample. Infrared spectroscopy can also be used to create a profile of known material, to test dirt deficiencies by checking the signatures that do not belong, and so on.
This type of work is carried out in a laboratory equipped with a spectroscope and a device that can be used to analyze the output. Many people use computer programs to visualize spectroscopy results as computer results can be easily manipulatedVat and study. People can also compare other results with the use of overlap and compositional programs, an activity that many people could see on crimes in which mysterious substances are identified using spectroscopy techniques.
