A theoretical study of the second band of the photoelectron spectrum of benzene with an analysis of the vibrational structure

Ab initio calculations have been performed to study the second band of the photoelectron spectrum of benzene with analysis of the vibrational structure. The ²E_{2 g} and ²A_{2 u} states contribute to this band. In this study each contribution to the band is discussed. We propose that the onset of the band should be assigned to the 0-0 transition of the ²A_{2 u} state. Received: 20 August 1998 / Accepted: 15 January 1999 / Published online: 7 June 1999
