Theoretical Studies of Transannular Interactions. IV. The Electronic States of the Paracyclophane Anion

Abstract
The π-electronic transition energies of the anion of the D6h benzene dimer have been computed at different interring separations. The transannular overlap is calculated using a carbon SCF atomic orbital. The numerical results are compared to the absorption spectra of the anion of [2,2] paracyclophane. Good agreement with the observed transition energies is found.
