Photoelectron and electron transmission (ET) spectroscopy were used to determine the ionization potentials and vertical electron attachment energies, respectively, of the 6+6 dimer of tropone. These measurements are combined with electronic structure calculations to provide insight into the extent of the coupling between the two cycloheptadienone ring systems. The ground state anion is predicted to be slightly stable as a consequence of the interaction between the π* orbital s of the C=O and butadiene groups.
