Congratulations on “Chemical Connections,” which summarizes the peculiar history of our understanding of the nature of the chemical bond (C&EN, Sept. 9, page 28). I agree with most of the article, ...

In 1923, the year C&EN was born, Gilbert N. Lewis of the University of California, Berkeley, published a book titled “Valence and the Structure of Atoms and Molecules.” In the text, Lewis laid out the ...

What makes some plastics stick to metal without any glue? Osaka Metropolitan University scientists have peered into the ...

Because bond order is a chemical concept, and not an observable in the quantum mechanical sense, there does not exist a unique definition of bond multiplicity in quantum chemistry. Thus, it is ...

Illustration of intracluster bond formation, cluster containing two biomolecules, being exposed to UV light (left), causes a chemical bond forming between the two molecules (center), resulting in a ...

Researchers resolve the age-old mystery of why silicon cannot replace carbon in organic compounds. A new benchmark quantum chemical calculation of C2, Si2, and their hydrides for the first time ...

Halogen bonding is a topic which continues to gain increased international attention across the chemical, biochemical, and materials sciences - this non-covalent interaction receiving a formal IUPAC ...

In this video, we explore the fundamental role of electrons in chemical reactions, rooted in quantum physics and the ...

We all remember the basic principles taught in high school chemistry class: There are three types of chemical bonds. However, covalent, ionic and metallic have a little competition now. There’s a new ...

Light-induced breakage of chemical bonds can lead to damage in the body and environment, but techniques for studying this photochemical reaction have been limited to before and after snapshots. With ...
