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 ...

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 ...

The hyperfine structure of atomic spectra arises from interactions between the electromagnetic moments of the atomic nucleus and the surrounding electrons. These interactions, dominated by the ...

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 ...

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 ...

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 ...

*If you learn how to use atomic absorption spectroscopy (AAS), you can do accurate and reliable chemical research. But it takes practice and concentration to fully grasp its basic ideas. Understanding ...
