Abstract
Infrared νCO (cm−1) of s-cis and s-trans frequencies and nuclear magnetic resonance chemical shifts δ1H (ppm) of H-α and H-β, δ13C (ppm) of C-α and C-β data were assigned from their respective spectra of a series of various substituted styryl 4-bromo-1-naphthyl chalcones. These values are correlated with various Hammett substituent constants. From the results of statistical analysis, the effect of substituents can be explained.
