Atomic Spectroscopy

Atomic spectroscopy studies about the electromagnetic radiation absorbed and emitted by atoms. In the determination of elemental compositions the electromagnetic spectrum or mass spectrum is applied that can be distributed by the type of spectroscopy used or with the atomization source. For systematic use the technology of atomic spectroscopy has generated three techniques such as Atomic Absorption, Atomic Emission and Atomic Fluorescence. The transitions involve the relaxation and excitation of the outer or bonding shell electrons of metal ions and atoms and the corresponding photons have energies inside the visible regions of the spectrum and ultraviolet. A decent instance of this is the dark absorption lines in the solar spectrum.
