Spectrometria

Spectrometria is a scientific technique used to measure the interaction between matter and electromagnetic radiation. It involves dispersing radiation that has been affected by a sample into its constituent wavelengths or frequencies. By analyzing the resulting spectrum, scientists can determine the composition, structure, and properties of the sample. The type of radiation used, such as light, X-rays, or infrared, dictates the specific type of spectrometry employed. For instance, UV-Vis spectrometry analyzes how a sample absorbs ultraviolet and visible light, providing information about its electronic structure. Infrared spectrometry, on the other hand, examines how a sample absorbs infrared radiation, which is characteristic of its molecular vibrations. Mass spectrometry is another related technique that measures the mass-to-charge ratio of ions, allowing for the identification and quantification of chemical substances. Spectrometric methods are widely used across various fields, including chemistry, physics, astronomy, environmental science, and medicine, for tasks ranging from identifying unknown compounds to studying distant stars.
