The PE. spectrum of [18]annulene has been measured and correlated with MO‐calculations. 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 states. The results allow a discussion of the structure of the neutral molecule; they are consistent with a D 6h point group of symmetry.
