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 • Biological pigment • Chromatophore • Fluorophore See more An auxochrome is a functional group of atoms attached to the chromophore which modifies the ability of the chromophore to absorb light, … See more Halochromism occurs when a substance changes color as the pH changes. This is a property of pH indicators, whose molecular structure changes … See more • Causes of Color: physical mechanisms by which color is generated. • High Speed Nano-Sized Electronics May be Possible with Chromophores - … See more WebJun 18, 2014 · 12. With respect to the Chromophore concept and electronic transition the following points can be noted: Spectrum with a band near 300 nm may contain 2 – 3 conjugated units. Absorption bands near 270 – 350 nm with a very low intensity of εmax 10 – 100 are due to n - * transition of the carbonyl groups. Simple conjugated chromophores …
