Opis:: About ten (Z)-1-(1-(substitutedphenyl)ethylidene)-2-(diphenylmethylene)hydrazines were prepared and their purities were examined by literature method. The infrared and NMR spectra of these hydrazines were recorded. The characteristics C=N and N-N stretches (ν, cm-1) and the chemical shifts (δ, ppm) of methyl protons and carbons were assigned. These spectral have been correlated with Hammett substituent constants, F, R and Swain-Lupton’s parameters using single and multi-regression analysis. From the results of statistical analyses, the effects of substituent on the spectral data have been studied.

Opis:: A series of substituted 2-((phenyl amino)methyl)-1,2-dihydro-5-(3-methoxyphenyl)-1-phenyl-1,2,4-triazole-3-thione compounds were synthesized and examined their purities as per the literature. The IR spectra of νC=N, νC=S, νNH and νCOC frequencies and NMR chemical shifts (ppm) of δNH, δOCH3, δCH2, δC=N, δC=S, δOCH3 and δCH2 are also assigned. The assigned IR and both 1H NMR and 13C NMR spectral data have been correlated with Hammett substituent constants and Swain-Lupton’s parameters using single and multi-linear regression analysis. From the results of statistical analysis, the effect of substituents on the above spectral data has been studied.
