The He I photoelectron and ultraviolet spectra of persubstituted 1,3-dicyanobenzenes were recorded. The electronic structure of the compounds was analyzed with the aid of empirical arguments and PM3 MO calculations. The caveats related to the analysis of substituent effects were examined, and the variation in ultraviolet intensities was attributed to rotamer populations and N-H-Cl hydrogen bonds.
