chromophore(Noun) that part of the molecule of a dye responsible for its colour. chromophore(Noun) (more generally) the group of atoms in a molecule in which the electronic transition responsible for a given spectral band is located.
Pigments are molecules with their own characteristic absorption spectra in response to light. The perceived color of the pigment depends upon the wavelengths of light that are not absorbed.A chromophore is the moiety within the pigment molecule that is responsible for the molecule's color. The chromophore possesses two orbitals whose difference in energy falls within the light spectrum.bsorption Spectrum: results from the ability of pigments to absorb incident electromagnetic radiation. Like the action spectrum, the parameter of interest (light absorbed) is plotted as a function of the wavelength of the radiation.
