Single and multi-correlation analysis
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.

Hammett equation
Correlation analysis
Opis:: A series containing ten titled compounds have been synthesised and recorded the IR and NMR spectra. From the spectra the infrared νNH, C=N, C-O-C stretches, NMR chemical shifts of (δ, ppm) NH and C=N were assigned and correlated with Hammett substituent constants, F and R parameters using single regression analysis. From the results, the effects of substituent on the above spectral frequencies were discussed.

Correlation analysis
Opis:: A series of some 2-bromo-1-(2-substituted 9H-fluorene-7-yl)ethanones have been prepared. The purities of these ethanones have been checked by their physical constants and spectroscopic data. The spectral group frequencies of these enones have been assigned and correlated with Hammett substituent constants, F and R parameters. From the results of statistical analyses, the effects of substituent have been discussed.

Hammett equation
IR and NMR spectra
QSAR study
Opis:: About nine titled compounds were synthesized by greener method and the purities of these methanones have been examined using their analytical and spectral data reported in literature. The infrared and NMR spectral data of these methanones were assigned and correlated with Hammett substituent constants, F and R parameters using single and multi-linear regression analysis. From the results of statistical analyses, the effects of substituents in terms of spectral quantitative structure activity on the spectral frequencies were studied.
