The electronic interactions between bridging (Y) and ring (X) substituents of aromatic compounds 4-X1C6H4YC6H4X2-4 (where Y = CO, NH; X1, X2 = H, NO2, MeO, Me2N) were studied by using ir spectra (¦ÍCO, ¦ÍNH) of CCl4, C2H4Cl2, and THF solutions Both ¦ÍCO and ¦ÍNH show solvent effects. The ¦¤¦Í values (referred to unsubstituted compounds) are discussed in terms of X and Y electron-donor or -acceptor capacity and the relation between X1 and X2 conjugation effects. The ¦¤¦Í values of X1 and X2 are non-additive (always less than the sum). Correlations ¦¤¦ÍCO/¦¤E1/2, ¦¤¦ÍNH/¦¤E1/2 (¦¤E1/2 = half-wave potential) and ¦¤¦ÍCO/¦Ò Jaffe are found. If X1 = X2 the ring substituent effect is concurrent with that of Y. If X1 and X2 are not the same, the predominant effect is the effect of X which has the sign for the conjugation effect opposite, to that of Y.
