1,4-Dibromonaphthalene is a molecule that has been studied extensively as an organic semiconductor. It is a crystalline solid with a low melting point and good solubility in organic solvents. 1,4-Dibromonaphthalene can be used as a model system to study exciton interactions and the optical properties of naphthalenes. The structure of 1,4-dibromonaphthalene has been determined by X-ray crystallography, showing that it is made up of alternating single and double bonds with four bromine atoms at each end. The molecule contains no hydrogen atoms and has the lowest possible energy state for its electronic interaction. Magnetic resonance spectroscopy studies show that this molecule is diamagnetic (has no unpaired electrons). The molecular symmetry is D2h (dihedral angle 180°) and the crystal symmetry is P2(1) (point group). This means that there are two different mirror
