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 ...

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 ...

From the locked geometry of cis-trans isomers to the invisible tug-of-war of molecular polarity, chemistry’s building blocks determine how substances behave. These structural differences influence ...

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

Structures made out of building blocks can shift their shape and autonomously self-organize to a new configuration. The physicists revealed this mechanism which may be used to actively manipulate ...
