Chromophoric groups
WebAuxochrome is a group of atoms which is functional and has the capability to alter the capacity of the chromophore to reflect colors. Azobenzene is an example of a dye which contains a chromophore. All substances like dyes produce colors by absorption of visible light owing to the various constituent compounds. The electromagnetic spectrum has ... http://www.isca.in/rjcs/Archives/v2/i7/7.ISCA-RJCS-2012-086.pdf

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 absorption. See more • Biological pigment • Chromatophore • Fluorophore See more Halochromism occurs when a substance changes color as the pH changes. This is a property of pH indicators, whose molecular structure changes upon certain changes in the surrounding pH. This change in structure affects a chromophore in the pH indicator molecule. … See more • Causes of Color: physical mechanisms by which color is generated. • High Speed Nano-Sized Electronics May be Possible with Chromophores - Azonano.com See more Webchro·mo·phore. n.
