noun a band of wavelengths in the electromagnetic spectrum that are absorbed by a particular substance
In environmental science, absorption bands are important for analyzing pollutants in the atmosphere and monitoring environmental changes.
In chemistry, an absorption band refers to a range of wavelengths in the electromagnetic spectrum where a substance absorbs light. This absorption is due to electronic transitions within the molecule.
In physics, absorption bands are used to study the interactions of electromagnetic radiation with matter, providing information about the structure and properties of materials.
In biology, absorption bands are utilized in techniques like infrared spectroscopy to study biomolecules and their interactions.
In materials science, absorption bands are analyzed to understand the optical properties of materials, such as semiconductors, polymers, and nanoparticles.
In spectroscopy, an absorption band is a characteristic feature in the spectrum of a substance, indicating the presence of specific functional groups or chemical bonds.
In chemistry, absorption bands are used to analyze the structure of molecules by studying the wavelengths at which they absorb light.
Physicists use absorption bands to study the energy levels of atoms and molecules, as well as to analyze the composition of materials.
Biologists may use absorption bands to study the interactions between light and biological molecules, such as pigments in plants.
Astronomers use absorption bands in the spectra of stars and galaxies to determine their composition and temperature.
