Spectral Shifts: Definition, Types, Factors, and Applications

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 Spectral Shifts 1. Bathochromic Shift […]

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 […]
