What is the IR spectrum database?
Infrared or IR database spectrum contains information about the reaction between infrared light and inorganic and organic substances. Molecules absorb infrared light in different degrees based on their overall structure. Using spectroscopy, these results graph these results and send them to the IR spectrum database. Chemists, forensic specialists and scientists often test unknown substances and compare results with a database, resulting in positive identification. Scientists also divide the spectrum into three sections, close, medium and far. Molecules are constantly moving and vibrating. When exposed to infrared light, parts of the molecules may absorb light when electrical frequencies correspond to the frequencies of the infrared spectrum. Spectroscopy measures the levels of absorption and displays the results on the interpretation chart.
The horizontal liniegraph represents frequency in the infrared spectrum. The vertical axis indicates the percentage of the light. The non -absorption appears as a line horizontally through the top of the chart andIt illustrates 100 percent of the beam. As compounds or substances absorb light, molecules vibrate. Scientists call specific movements that molecules show according to conditions that include rocking, scissors and stretching.
These movements appear on the chart as a lines immersion and creating reverse peaks that stop at the percentage level of the remaining infrared light. Scientists call these peaks and valleys of the band. The length and width of the belts depends on the absorption speed, intensity and type of movement displayed. Different compounds show the bands unique to this substance and act as an otis finger for identification. IR Spectra database contains graphs of these test compounds.
When testing unknown substances, IR spectrum database contained in spectroscopes, it generally compares test results with known data and identifies compounds in the substance. IR Spectrum database is also useful for verificationOmnosti suspicious substances, including alcohol. Forensic scientists regularly use infrared spectroscopy and IR database to identify drugs, fibers and color samples. Forensic specialists can determine the death period by analyzing bone cells of the deceased individual using IR technology.
Pharmaceutical Industries often applies to the IR spectrum database for determining the type and purity of herbs contained in over -the -counter. Biological scientists require information in determining the presence of pollutants in the environment. Using spectroscopy and database IR Spectra analysts often determine the identity of gases, liquids and solids.
