X-ray absorption spectroscopy (XAS) measures the transmission of a substance as a function of the incident photon energy E in the X-ray regime. It is element-specific and orbital-specific, enabling ...
X-ray spectroscopy plays a pivotal role in understanding the geometric and electronic structures of countless molecules and materials, from homogeneous and heterogeneous catalysts to biological active ...
(Image: Argonne National Laboratory) Here’s how XANES works: Scientists shine X-ray beams with increasing energy onto a material. Each X-ray beam is a tiny packet of energy. When the energy is high ...
Realizing attosecond core-level x-ray spectroscopy for the investigation of condensed matter systems
The many-body interaction of charges (electrons) and nuclei (phonons) plays a critical role in determining the properties and functionalities of molecules and solids. The exact correlated motion of ...
