文摘Gas-phase HeI ultraviolet photoelectron spectra of m-dicyanobenzelle, P dicyanobenzene and 1,2,4,5-tetracyanobenzene are given in this paper. Photoelectronspectra are assigned using MNDO molecular orbital calculation and correlation analysisfor benzene and each cyanobenzene. It may be pointed out that there is some effect of thesubstituted position and numbers of -CN group on the relative ordering levels, splittingsand the levels of the two orbitals splitted by elg(π) of benzene.
