Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules attract and hold one molecule to another. Image Water and Alcohol Molecules. Alcohol has ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

Polar molecules in an optical lattice provide a versatile platform to study quantum many-body dynamics. Here we use such a system to prepare a density distribution where lattice sites are either ...

"The focal point of our research has been the design of polar crystalline solids of pure molecular materials for nonlinear optics," says Bhoday. "Rather than merely seeking these crystals, ...
