absorption band
one of any number of ranges of wavelengths of electromagnetic radiation absorbed by a substance
the wavelength range over which electromagnetic energy is absorbed by a material (e g , a mineral, rock, or atmosphere) and has an emissivity less than 1 0
The wavelength interval(s) at which electromagnetic energy is absorbed rather than reflected or scattered
In atmospheric radiative transfer, a collection of absorption lines in a particular frequency interval
a dark band in the spectrum of white light that has been transmitted through a substance that exhibits absorption at selective wavelengths
A 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 are converted to simultaneous changes in more than one of the electronic, vibrational, or rotational molecular energy states Changes to vibrational energy are usually accompanied by changes in rotational energy and give rise to vibrational-rotational absorption bands Similarly, changes to molecular electron levels yield electronic-vibrational-rotational absorption bands
  A spectral region in which the absorption coefficient reaches a relative maximum, by virtue of the physical properties of the matter in which the absorption process takes place   [FAA]
