ab·sorp·tion band

the 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 colorimetry or spectrophotometry, and is usually described in terms of the wavelength where maximum absorbance occurs (that is, λmax).

Ketonic compounds are also formed during UV irradiation of PVC and were detected by the absorption band at 1725 [cm.
However, while a "pure" spectrum of the coating may not necessarily be isolated in this manner, if a suitable window is available within the substrate's mid-infrared spectrum in which an absorption band of the coating is present, a coating layer thickness may be determined to a much lower thickness value.

The absorption band shifts when moving from one solvent to another.
Jadeites with an `apple-green' color, had a broad absorption band on the red site of the spectrum from 700 nm and extending beyond 1000nm.
Because each individual component contributes a complex set of several absorptions falling within the mid-IR spectral region, it is impossible to find any single absorption band that can serve as the basis to quantify any single component; coincident absorptions from other species would degrade or completely sabotage the effort.
Renge studied the spectral responses of porphyrins in a series of nonpolar n-alkanes which vary in refractive index, and characterized a definite dependence of the absorption band energies upon the polarizability of the solvent (Renge 1993; Renge 1991).
These higher temperatures are designed to coincide with the most familiar infrared absorption band of plastics, lying between 3.
