absorption bandA connected series of closely spaced or overlapping absorption lines. Absorption bands are common features in the absorption spectra of polyatomic gases. Absorption bands arise when absorbed photons a [..]

absorption band(physics),(chemistry) one of any number of ranges of wavelengths of electromagnetic radiation absorbed by a substance

5 |
absorption bandThe range of wavelengths or frequencies in the electromagnetic spectrum where radiant energy is absorbed by passage through a gaseous, liquid, or dissolved substance; it is exploited for analytical purposes in colourimetry or spectrophotometry, and is usually described in terms of the wavelength where maximum absorbance occurs (i.e., lambdamax).
