Spectral shifts refer to changes in the position of the absorption or emission peaks of a molecule in a spectrum, often resulting from changes in the molecule’s environment, structure, or interactions. These shifts occur in response to variations in solvent polarity, pH, temperature, or the presence of substituents. Types of …

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 …
