Atomic Absorption Spectroscopy (AAS) is an analytical technique used to determine the concentration of metal elements in samples by measuring the absorption of light. It relies on the principle that free atoms in the ground state can absorb light at specific wavelengths, which is directly related to the concentration of the element in the sample.

The ground state of a quantum system is its lowest energy state, where the system is in its most stable configuration. Understanding the ground state is crucial for predicting the behavior of atoms and molecules, as it determines the baseline from which all excited states and quantum transitions are measured.
