Abstract :
[en] The threshold photoelectron spectrum (TPES) and the constant ion state (CIS)
spectra of the individual ionic states of C2H3F have been recorded using
synchrotron radiation. For comparison a well resolved HeI photoelectron spectrum
(HeI-PES) has also been measured and analyzed in detail. The TPES has been
measured between 9.5 eV and 35 eV photon energy. Numerous vibrational
structures, reported for the first time, observed in the ground state and the six
excited states of the cation are analyzed. Quantum chemical calculations have been
performed and provide strong support to the assignments. State selected CIS
spectra highlighted the major importance of autoionization for the production of
almost all ionized states of C2H3F observed in this work.
