Single photon simultaneous core ionization/core excitation (K −2 V) of the Benzene molecule has been observed experimentally, using synchrotron radiation, by electron coincidence spectroscopy with a magnetic bottle time-of-flight electron spectrometer and reveals a rich spectrum. DFT and Post–Hartree–Fock calculations provide detailed assignments of K −2 V states. The specific Auger decay of these states has also been determined experimentally with a new technique to improve the energy resolution.
