Atomic spectroscopy is a technique that examines the characteristic energy values ​​and structures of atoms within molecules. This method is used to determine the spectral characteristics of atomic and molecular particles. Atomic spectroscopy is performed through a variety of experiments using different spectral techniques. These techniques include atomic absorption spectroscopy, atomic emission spectroscopy, laser spectroscopy, and X-ray spectroscopy. Atomic spectroscopy is used as an important tool in many fields such as chemical analysis, material characterization, biochemistry and environmental sciences. These techniques provide valuable information for determining the presence, quantity, and composition of elements, studying reaction mechanisms, and understanding molecular structures. Atomic spectroscopy is also used in the medical field, playing an important role in the analysis and diagnosis of biological samples.
