Field and charge-transfer theory for the quantitative correlation of substituent effects in aromatic molecules. Part I. The field and charge-transfer (FCT) theory

Abstract

The principles of the previously suggested title theory of substituent electronic effects on aromatic molecules are clarified and the question of how best to apply the theory is discussed. It is shown how FCT theory may be regarded as an extension of Swain and Lupton's version of that theory of substituent effects normally used by organic chemists. The potential advantages of the FCT treatment over Swain and Lupton's treatment are stated.
