WebThe partial structures necessary for color (unsaturated groups that can undergo π → π * and n→ π * transitions) are called chromophores. Some common chromophores are: A dye is a colored organic compound that is used to impart color to an object or a fabric. 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 … See more Just like how two adjacent p-orbitals in a molecule will form a pi-bond, three or more adjacent p-orbitals in a molecule can form a conjugated pi-system. In a conjugated pi-system, electrons are able to capture certain photons as … See more An auxochrome is a functional group of atoms attached to the chromophore which modifies the ability of the chromophore to absorb light, altering the wavelength or intensity of the … See more • Biological pigment • Chromatophore • Fluorophore • Litmus See more Halochromism occurs when a substance changes color as the pH changes.
