Adiabatic ionization energy (AIE) and two-color threshold ion vibrational spectra of p-fluorostyrene have been measured by mass analyzed threshold ionization (MATI) method via three different intermediate levels in the first excited state, vibrationless S1 origin, 421411, and 231 vibronic levels. Features of the ion vibrational spectra indicates that the geometry of the molecular ion including the conformation of the vinyl chain in the ionic ground state(D0) is almost identical to that of its neutral ground state(S0), and ionization has very little effect on the vibrational potentials of the aromatic ring modes. Comparison of the AIE with the reported value of styrene shows that fluorination at the para position of the aromatic ring has little effect on energy of the electron ejected in ionization process from the styrene chromophore.
