An orbital structure is the space in an atom that’s occupied by an electron. But when describing these super-microscopic properties of matter, scientists have had to rely on wave functions — a ...

The first direct observation of the orbital structure of an excited hydrogen atom has been made by an international team of researchers. The observation was made using a newly developed “quantum ...

The first direct observation of the orbital structure of an excited hydrogen atom, made using a newly developed "quantum microscope." (Stodolna et al. / Physical Review Letters) Image 2 of 2 ...

And a molecule's structure is set by the rules of quantum mechanics. In principle, if you could solve Schroedinger's equation for a molecule, ... Consider a hydrogen atom.

In quantum tunneling, the hydrogen atoms can move through barriers ... "This is the first observation of hydrogen-atom tunneling diffusion ... whereas polycrystalline ice has a periodic structure.

Part I, appearing in July 1913, described the quantum rules for electron orbits and quantum jumps in the hydrogen atom, explaining the spectrum of colors it emitted.

The Bohr model is a neat but quite imperfect depiction of the inner workings of an atom before things got too muddled up by quantum principles.

Imidazoles and triazoles are essential chemical compounds used in many medicines, including drugs used to defeat various pathogen-induced infections and cancer. Besides these applications, both ...

Some subtle quantum effects slightly alter those energy levels. One such tweak — the Lamb shift — surprised physicists when it was reported in hydrogen atoms in 1947.
