Some correlations between the structures of acylhydrazines and N, N'-diacylhydrazines and their chemiluminescence efficiencies have been determined. A comparison of the chemiluminescence spectra of the hydrazides of 1-hydroxy-haphthoic acid and of 1-hydroxy- Zanthroic acid and the fluorescence spectra of the corresponding carboxylate ions in dimethyl sulfoxide indicates that the latter compounds may be the emitters in the ...
