We report zero kinetic energy (ZEKE) photoelectron spectroscopy via resonantly enhanced multiphoton ionization (REMPI) for benzo[e]pyrene. Extensive vibronic coupling between the first electronically excited state and a nearby state allows b 2 modes to be observed which would be Franck–Condon (FC) disallowed. These vibronic modes are comparable in intensity to the FC allowed a 1 modes. We are able to qualitatively simulate the vibronic spectra of both REMPI and ZEKE using density functional methods. The ZEKE spectra demonstrate propensity in preserving the vibrational excitation of the intermediate state. These results suggest a remarkable structural stability of BeP in accommodating the additional charge.
