Absorption Band

Definition of Absorption Band from the PharmacyDictionary.in

Absorption Band

A region in an absorption spectrum of a substance where the absorptivity reaches a maximum. This is an inflection point in the spectrum. An “Absorption Band” is a spectrum section of wavelengths, frequencies, or energies. It’s unique to a specific transition from an initial to a final state in a substance. This idea is essential in quantum mechanics and spectroscopy.
