absorption spectrum (absorption spectra)
Compare with absorption spectroscopy .A plot that shows how much radiation a substance absorbs at different wavelengths . Absorption spectra are unique for each element and compound and they are often used as chemical "fingerprints" in analytical chemistry.

Absorption spectrum
A material's absorption spectrum shows the fraction of incident electromagnetic radiation absorbed by the material over a range of frequencies. An absorption spectrum is, in a sense, the opposite of an emission spectrum. Every chemical element has absorption lines at several particular wavelengths corresponding to the differences between the energy levels of its atomic orbitals. For example, an object that absorbs blue, green and yellow light will appear red when viewed under white light. Absorption spectra can therefore be used to identify elements present in a gas or liquid. This method is used in deducing the presence of elements in stars and other gaseous objects which cannot be measured directly.
