Chromophore - an overview ScienceDirect Topics

A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore is a region in the molecule where the energy difference between two separate molecular orbitals falls within the range of the visible spectrum. Visible light that hits the chromo… WebAluminum oxide, also known as corundum or colourless sapphire when pure, can serve as an example. In this compound each trivalent aluminum ion is surrounded by six oxygens in the configuration of a slightly irregular octahedron. The electric field at the aluminum site of this octahedral arrangement of oxygens is known as the ligand field.
