Regression analysis - Opis:
- About nine 4-(substituted phenyl sulfonamide) benzoic acid derivatives were synthesized by ultrasound irradiation method. The synthesized sulfonamides were characterized by their physical constants and spectroscopic data. The characteristic infrared SOsym, SOasym, NH and CO vibrations (ν, cm-1), the chemical shifts (δ, ppm) of NH and CO of sulfonamides were assigned and correlated with various Hammett substituent constants and Swain-Lupton parameters using single and multi-regression analysis. From the results of the statistical analysis, the effects of substituents on the spectral frequencies were discussed.
