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 ...

Carboxylic acids are ubiquitous in bioactive organic molecules and readily available chemical building blocks. Carboxylic ...

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 ...

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.

The spin-flip transition of the hydrogen atom, for example, is the narrowest spectral line known in physics, and it's due to this hyperfine effect that goes beyond even fine structure.

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 ...

Scientists have captured the first ever photo of an electron’s whizzing orbit within a hydrogen atom, thanks to a unique new microscopy technique.

The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a ...
