Reaction rates and chemiluminescent and fluorescent spectra of six fully substituted tetraaminoethylenes were studied. The compounds were tetrakis-N-pyrrolidinylethylene, 1,1, 3,3-tetramethyl Delta 2,2-biimidazolidine, 1,1, 3,3-tetraethyl-Delta 2,2-biimidazolidine, 1,1, 3,3-tetra-n-propyl-Delta 2,2-biimidazolidine, 1,3-diethyl-1, 3-dimethyl Delta 2,2-biimidazolidine, and 1,1, 3,3-tetramethyl-Delta 2,2-bihexahydropyrimidine. Chemiluminescence emission wavelength are in each case identical to the fluorescence emission of the parent compound. A study was made of the effects of concentration of tetraaminoethylene, concentration of reacting oxygen, and concentration of a hydroxyl-containing catalyst n-octanol on the reaction rates of tetrakisN-pyrrolidinylethylene. An argument is presented relating the relative reaction rates of the six compounds to the degree of steric shielding of the ethylenic pi orbital. Modified author abstract
