A series of 6-substituted quanoxaline derivatives have been synthesized and examined their purities by literature method. The infrared and 13C NMR spectral data of these quinoxalines were correlated with Hammett substituent constants, F and R parameters using single and multi-regression analysis. From the results of statistical analysis, the effect of substituents on the spectral frequencies has been studied.
