摘要：

Double photoionization of CO2, OCS, C2H2, CF4 and C6H6 molecules has been studied in an electron-electron coincidence experiments, where nearly zero kinetic energy (less-than-or-equal-to20 meV) electrons are detected. This first application of TPEsCO spectroscopy to polyatomic molecules confirms the ability of this experimental technique to determine accurate double ionization potentials and locate excited electronic states. The spectrum of benzene reveals what appears to be the first observation of vibrational structure in a polyatomic dication.
