Scientists have achieved the first real-time visualization of how excited-state aromaticity emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to planar ...

VSEPR theory provides a practical way to predict the 3D shapes of molecules by focusing on how electron pairs repel each other. This model explains why atoms arrange in specific geometries, from ...

Certain cells have an unusual shape that is similar to an oak leaf or puzzle piece, and researchers have found that the form of these cells helps them withstand dramatic changes in volume. These cells ...

Electron spin can create differences between mirror-image molecules, a potential explanation for why life favors one ...
