Abstract
Infrared nuCO (cm(-1)) of s-cis and s-trans frequencies and nuclear magnetic resonance chemical shifts delta(1)H (ppm) of H-alpha and H-beta, delta(13)C (ppm) of C-alpha and C-beta 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.
