Opis:: A series containing nine 3-(substituted phenylsulfonamido)benzoicacids) have been synthesized and examined their purities by their data reported earlier. The characteristic infrared (NH, SO(as), SO(sym) and CO(as) cm-1) stretches, NMR chemical shifts (δ, ppm) of NH protons, CO carbons were assigned and correlated with Hammett substituent constants and Swain-Lupton’s parameters using single and multi-regression analysis.

QSAR and QPR study
Opis:: A series of titled compounds were synthesized and recorded the infrared and NMR spectra. The assigned spectral group frequencies were correlated with Hammett substituent constants, F and R parameter. From the statistical analysis results, the effect of substituents on the spectral group frequencies has been studied.

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.
