A bell shape correlation curve has been found for a plot of the Hammett ? constant and the quantum yields of the formation of excited amidines from the chemiluminescent reaction of 2-(p-dimethylaminophenyl)-4,5-di( p-X--phenyl)-4-hydroperoxy-4H-isoimidazoles (X= OCH3, H, F, Cl, CF3, and CN) with bases.
