Atomic and molecular structure as a research area investigates the spatial arrangement, electronic configuration, and intrinsic quantum properties of atoms and molecules, and how these features determine their spectroscopic, chemical, and physical behavior. It encompasses theoretical and computational methods (e.g., ab initio quantum chemistry, density functional theory, configuration interaction) and experimental techniques (e.g., high-resolution spectroscopy, scattering, synchrotron and XFEL-based probes) to resolve electronic states, bonding patterns, potential energy surfaces, and correlation effects. This field underpins understanding of reactivity, photophysics, materials properties, and the design of novel molecules, clusters, and nanostructures with targeted electronic and structural characteristics.
Accurately modeling particle movement through fluids is crucial in fields ranging from chemical engineering to aerospace. The drag coefficient, which influences how particles settle and move in fluid environments, is a core ...
