  • Title: Substituent and solvent effects on electronic absorption spectra of some N-(substitutedphenyl)benzene sulphonamides.
    Author: Suganya K, Kabilan S.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2004 Apr; 60(5):1225-8. PubMed ID: 15084341.
    Abstract:
    The effects of substituents and solvents have been studied through the absorption spectra of nearly 23 ortho- and para-N-(substitutedphenyl)benzene sulphonamides in the range of 200-400 nm. The effects of substituents on the absorption spectra of compounds under present investigation are interpreted by correlation of absorption frequencies with simple and extended Hammett equations. Effect of solvent polarity and hydrogen bonding on the absorption spectra are interpreted by means of Kamlet equation and the results are discussed.
