The Woodward Fisher Regulation for Calculating Absorption Maxima
Main Article Content
Abstract
Woodward regulations are countless units of empirically derived guidelines which try to predict the wavelength of the absorption most λmax in an ultraviolet-visible spectrum of a given compound. Inpute used in the calculation are the kind of chromophores present, the auxochromes substituents on the chromophores, and solvent. Example is conjugated carbonyl compound conjugated dienes, and polyenes. One set of Woodward-fishers policies for dienes is outlined is both homoannular with each double bonds contained in one ring or heteroannular with double bonds disbursed between two rings. With the useful resource of these regulations the UV absorption most can be predicted
