Question

What are chromophores?

Answer 1

Chromophore:

1. A chromophore is the part of a molecule that gives it its color.
2. Within a specific visible light wavelength spectrum, the color we experience is the color that is not absorbed by the reflecting item.
3. The chromophore is a component of the molecule in which the energy difference between two molecular orbitals is within the range of the visible spectrum.
4. Visible light that strikes the chromophore can be absorbed by stimulating an electron from its ground state to an excited state.
5. In biological molecules that assist capture or detecting light energy, the chromophore is the moiety that causes a conformational change in the molecule when it is touched by light.
