Abstract: The transmission of the substituent effect in several series of α,β-unsatd. arom. compds. was analyzed on the basis of SCF-LCI perturbation theory. The proposed approach permits not only the theor. calcn. of ρ for LFER between carbonyl stretching frequencies and substituent consts., σ, but also assignment of the actual conformation of α,β-unsatd. carbonyl compds.
