X-ray absorption spectroscopy (XAS) is a powerful technique used to determine the local geometric and electronic structure of matter by measuring the absorption of X-rays as a function of energy. It provides element-specific information and can probe the oxidation state, coordination environment, and chemical bonding of the absorbing atom in various materials, including solids, liquids, and gases.
Relevant Fields:
Concept
X-ray spectroscopy is a technique used to determine the elemental composition and electronic structure of materials by measuring the characteristic X-rays emitted from a sample when it is excited by a primary X-ray source. This method is crucial in fields such as chemistry, physics, and materials science for analyzing atomic and molecular structures with high precision.
Concept
X-ray absorption involves the attenuation of X-ray photons as they pass through a material, providing insights into the material's composition and structure. This technique is fundamental in fields such as medical imaging and material science, where it aids in the identification of elemental and chemical states through methods like X-ray absorption spectroscopy.
Concept
Chemical state analysis involves determining the electronic and structural environment of atoms within a material, providing insights into the material's composition, chemical bonding, and oxidation states.
