Abstract
The helium (I) photoelectron spectrum of C(CN)~4~ curiously displays ionizations only in two small windows from 13.8 eV to 14.5 eV and from 14.8 eV to 15.5 eV, respectively. A tentative assignment of the numerous overlapping bands β based on a spectroscopically parametrized LCBO MO model β correlates satisfactorily with ionization potentials of other cyano compounds as well as of tetrahalomethanes.

The hatched bands of "sulfine" can be deduced by comparison of the spectra (b) and (c). Their assignment follows from an ab initio SCF calculation ['1 and by comparison with SSO and OSO[51; it is supported by the resolved vibrational fine structures in the first three bands and by the change in the
## Abstract The PE. spectrum of [18]annulene has been measured and correlated with MOβcalculations. The experimental ionization energies can only be explained by computing the electronic states of the cation, that is by taking into account the electron correlation and reorganization in the ionic st
