benzene dimer

A benzene dimer is a pair of benzene molecules (rings of six carbon atoms with hydrogen atoms) that stick together through weak forces called pi-pi interactions. These interactions involve the overlapping of the electrons in the aromatic rings, creating a transient, stabilizing connection without forming strong chemical bonds. Benzene dimers help scientists understand molecular interactions in organic chemistry and are relevant in processes like materials design and drug development. Essentially, they are two benzene rings held close by subtle forces, showcasing how molecules can associate through their electron clouds even without forming traditional bonds.
