Abstract :
Resonant photoemission from the fluoromethane (CH3F) molecule has been measured with photon energies scanning through the resonance in which a C or F 1s electron is promoted to the lowest unoccupied molecular orbital σ CF ∗ . The spectator Auger band with the lowest binding energy of ∼27 eV is tentatively assigned to 2e−26a1. The energy-resolved electron–ion coincidence experiments revealed that this state produces predominantly CH 2 + ions both for C 1s and F 1s excitations, providing evidence that the spectator Auger decay to this state takes place within the molecular regime, where the valence electrons are delocalized over the entire molecule.
