Substituted cyanopyridine
Opis:: About ten substituted cyanopyridine compounds have been synthesized and the purities of these pyridines were examined with their physical constants, analytical and spectroscopic data provided in the literature. They are characteristic infrared stretches and NMR chemical shifts were assigned and they are correlated with Hammett substituent constants using single and multi-linear regression analysis. From the results, the effect of substituents on the spectral data of cyanopyridine has been discussed.

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.

Single and multi-regression analysis
Opis:: Single and multi-regression analysis was applied for the corrosion study of transmission of substituent effects on IR carbonyl stretching frequencies and 13C chemical shifts of some substituted oxazepin compounds. The substituent effects were estimated on the basis of results of the statistical analysis. The differences among the obtained regression coefficients were discussed in terms of the relative importance of the field, inductive and resonance effects of substituent.
