Intrinsic delocalized electrical effect parameter

The intrinsic delocalized (resonance) electrical-effect parameter. It represents the delocalized electrical effect in a system with zero electronic demand, ffe The electronic demand sensitivity parameter. It adjusts the delocalized effect of a group to meet the electronic demand of the system, ffp A composite delocalized electrical-effect parameter which is a function of and (Tj.Examples of Cd constants are the o-r and % constants.The o-r i constants, where k designates the value of the electronic demand q, are also examples of [Pg.435]

Ui is the intrinsic delocalized (resonance) electrical effect parameter it represents the delocalized electrical effect in a system with no electronic demand.
