Woodward's rules, named after Robert Burns Woodward and also known as Woodward–Fieser rules (for Louis Fieser) are several sets of empirically derived rules which attempt to predict the wavelength of the absorption maximum (λmax) in an ultraviolet–visible spectrum of a given compound. Inputs used in the calculation are the type of chromophores present, the substituents on the chromophores, and shifts due to the solvent. Examples are conjugated carbonyl compounds, conjugated dienes, and polyenes.
