If you repeat a measurement with the same or different instruments, you'll get slightly different numbers each time. Estimating the uncertainties associated with these numbers turns them into an ...

Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have developed a novel method for investigating the internal structure of atoms and discovered ...

The study of atomic structure and spectroscopy under relativistic conditions unites quantum mechanics with the theory of relativity to describe electrons moving at speeds approaching that of light. In ...

Yuri Ralchenko led one of the oldest teams at the National Institute of Standards and Technology. The fate of some experiments hangs in the air. Lost Science Yuri Ralchenko led one of the oldest teams ...

Researchers have observed hydrogen and deuterium molecules in tiny spaces called picocavities using advanced spectroscopy. This study reveals unique differences between the molecules due to quantum ...

NMR (Nuclear Magnetic Resonance) spectroscopy is a powerful analytical technique that provides detailed information about the structure, dynamics, and chemical environment of molecules at the atomic ...

The Journal of Analytical Atomic Spectrometry (JAAS) is the central journal for publishing innovative research on fundamentals, instrumentation, and methods in the determination, speciation and ...

What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...
