Halogen bonding (XB), the attractive interaction between an electron-deficient halogen atom and a Lewis base, has undergone a dramatic development as an intermolecular force analogous to hydrogen ...

Using a technique called high-resolution atomic force microscopy (AFM), researchers in China have visualized the molecular structure of a hydrogen bond. Image: AFM images of 8-hydroxyquinoline on a ...

Hydrogen bonds are ubiquitous—and universally important—in chemistry. They give water its unique properties, speed or slow reactions, and hold together the three-dimensional shapes of DNA, proteins, ...
