a dark band in the absorption spectrum of a substance, corresponding to a range of wavelengths for which the substance absorbs more strongly than at adjacent wavelengths.
Where the curve is highest there the absorption band is thickest; where the curve is lowest there the band is weak.

absorption chromatography absorption chromatography n. See chromatography.
- Absorption coefficient
a measure of the rate of decrease in the intensity of electromagnetic radiation, as light, as it passes through a given substance. absorption coefficient n. The milliliters of a gas at standard temperature and pressure that will saturate 100 milliters of liquid. The amount of light absorbed in 1 atom or in 1 unit of […]
- Absorption costing
noun a method of cost accounting in which overheads are apportioned to cost centres, where they are absorbed using predetermined rates Compare marginal costing
- Absorption edge
a discontinuity in the graph of the absorption coefficient of a substance plotted against the wavelength of x-rays being absorbed, representing the minimum energy necessary to free electrons from particular shells of the atoms of the substance.
- Absorption dynamometer
a device for measuring the torque or power of an engine in a process in which the energy supplied to the device by the engine is absorbed.
