✦ Synopsis

The He@) photoelectron spectra of eight tazapentalenes, substituted in 1,3-position by electron releasing groups (dimethylamino, ethoxy, and tert-butyi) revealed that the first four ionization energies (6.4-9.3 eV) are due to ionziation from n MOs. This assignment is based on the comparison with the PE data of 1,3bis(dimethy1amino)pentalene (10) and the results of MNDO calculations. The comparison between experiment and calculations suggests that the first two bands are due to ionizations from x MOs mainly localized in the pentalene moiety.
