WebJan 1, 2015 · Thus, the existence of chromophoric group in the macromolecules is a prerequisite for the initiation of any photochemical reaction (Schnabel 1981). Ketones, quinines, and peroxides are initiators for different reaction degradation or chemical modification occurring in organic compounds (Kaczmarek et al. 1999). They absorb light … WebOct 19, 2016 · Some of the important chromophores are: ethylene, acetylene, carbonyls, acids, esters and nitrile groups etc. A carbonyl group is an important chromophore, although the absorption of light by … 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.
