Abstract
Effect of substituent and solvent on the electronic spectra of some substituted styryl pyrrolyl ketone
The effects of substituents and solvents have been studied through the absorption spectra of nearly twelve meta, para and ortho-substituted 2-pyrrolyl styryl ketones in the range of 200-400 nm. The effects of substituents on the absorption spectra of compounds under investigation are interpreted by correlation of absorption frequencies with simple and extended Hammett equations. With the help of Kamlet equation the effect of solvent polarity and hydrogen bonding on the absorption spectra are interpreted and the results are discussed
