New features were observed by us in the Rydberg series of benzene converging to the second ionization limit. A new interpretation of the vibronic structure and vibronic intensity pattern is presented. An interesting vibronic coupling scheme in which four very nearly degenerate electronic states participate is considered. On the basis of our new experimental observations and the new theoretical analysis presented in this paper we are able to assign the second ionization process in benzene as taking place from the 3e2g-σ orbital. It is shown that previous vibronic analyses have not given a proper and full description of the problem.
