Auxochromes: Definition, Characteristics, Types, and Applications
An auxochrome is a functional group that does not itself absorb light in the visible spectrum but, when attached to a chromophore, modifies the chromophore’s ability to absorb light. It enhances the absorption intensity and often shifts the wavelength of maximum absorption (λmax)of the chromophore. Characteristics of Auxochromes 1. Functional Groups: Auxochromes typically contain lone…
