| Abstract: | Substituent constants (a) of chalcone conjugated compounds I; R = H, m-NO2, p-Br, p-Ph; X = H, Me, MeO, Cl, NO2] were determine and showed a linear relationship with lmax. A linear relationship was also observed between the log of rate constants and Hammett reaction constant s with g > 0.98. |
