ABSORPTION BAND Meaning and
Definition
-
An absorption band refers to a specific range of wavelengths within the electromagnetic spectrum that are absorbed by a substance. It is a characteristic feature that can be observed in spectroscopy, particularly in the field of molecular spectroscopy. When electromagnetic radiation, such as light or radio waves, passes through a sample material, it may interact with the atoms and molecules present in the sample. This interaction leads to the absorption of specific wavelengths of radiation by the substance, resulting in the formation of absorption bands.
These absorption bands are caused by the transitions of electrons within atoms or the vibrations and rotations of molecules. Each substance has its own unique absorption bands, determined by its molecular structure and composition. By analyzing these absorption bands, scientists can obtain valuable information about the composition and properties of a sample material.
Absorption bands are typically represented as peaks or dips in a graph, known as an absorption spectrum, which displays the intensity of absorbed radiation as a function of wavelength. The shape, position, and intensity of absorption bands can provide valuable insights into the molecular structure, concentration, and purity of a substance.
Overall, absorption bands play a crucial role in various scientific disciplines, including chemistry, physics, astronomy, and environmental science, enabling researchers to study and identify the fundamental properties of different materials and substances.

Etymology of ABSORPTION BAND
The etymology of the word "absorption" can be traced back to the Latin word "absorptio", which means "a swallowing up" or "a taking in". It is derived from the verb "absorbere", which combines "ab" (meaning "away") and "sorbere" (meaning "to suck in" or "to swallow").
The word "band" has a different origin and comes from the Old Norse word "bönd", which means a "strip" or "ribbon". It later evolved into the Middle English word "bande", referring to a decorative strip of cloth worn around the head.
Therefore, when combined to form "absorption band", the term refers to the spectral region or range in which a substance absorbs electromagnetic radiation.
