Noun
the spectrum of electromagnetic radiation that has passed through a medium that absorbed radiation of certain wavelengths
Source: WordNetAccordingly, the technique of "Fourier transform spectroscopy" can be used both for measuring emission spectra (for example, the emission spectrum of a star), and absorption spectra (for example, the absorption spectrum of a liquid). Source: Internet
Color blindness involving the inactivation of the short-wavelength sensitive cone system (whose absorption spectrum peaks in the bluish-violet) is called tritanopia or, loosely, blue–yellow color blindness. Source: Internet
Katz, 374 Solution C 60 solution Optical absorption spectrum of Cmain solution, showing reduced absorption for the blue (~450 nm) and red (~700 nm) light that results in the purple color. Source: Internet
This range is sometimes called the fingerprint region, since the mid-infrared absorption spectrum of a compound is very specific for that compound. Source: Internet
The ratio of the "sample spectrum" to the "background spectrum" is directly related to the sample's absorption spectrum. Source: Internet
