The C6F5X＋ (X＝Cl, Br, I, CH3) cations were studied using the DFT B3LYP method in conjunction with the 6-311G (d,p), 6-311＋G (d,p), and LanL2dz basis sets. The geometries of the electronic ground-state cations were optimized and the vertical ionization potential (VIP) and adiabatic ionization potential (AIP) of the parent molecules were calculated. The calculated results indicated that the symmetries of the four cations are same as their parent molecules, while the geometric parameters are different. The B3LYP/6-311＋G (d,p) calculated vertical ionization potential and adiabatic ionization potential values of the C6F5X (X＝Cl, Br, I, CH3) molecules are in good agreement with the available experiments.

Key words: C6F5X＋ (X＝Cl, Br, I, CH3), ionization potential, B3LYP
