Spectral Correlations in some Substituted Styryl (<i>E</i>)-4-((2-Oxopropyl)Diazenyl) Benzoic Acids

Abstract

A series of titled compounds were prepared and analyzed their purities by literature method. The infrared and NMR spectral group frequencies of the compounds were assigned and correlated with Hammett substituent constants, F and R constants using single and multi linear regression analysis. From the results of statistical analysis, the effect of substituents on the above spectral frequencies was discussed.
