These are referred to as atomic absorption spectroscopy and flame photometry respectively. PRINCIPLES AND APPLICATIONS OF ATOMIC ABSORPTION SPECTROSCOPY. The underlying principle of atomic absorption spectroscopy (AAS) is the absorption of energy exclu-sively by ground state atoms while they are in the gaseous form. In order to un - derstand the relationship of these techniques to each other, it is necessary to have an understanding of the atom itself and of the atomic process involved in each technique. Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state.Atomic absorption spectroscopy is based on absorption of light by free metallic ions.
