The multiconfiguration second-order perturbation theory (CASPT2) and complete active space self-consistent field (CASSCF) methods were employed to calculate the geometries and energy levels for the low-lying electronic states of 1,3,5-C6H3Cl3 + ion. The CASPT2 values for the 1,3,5-C6H3Cl3 + ion were in reasonable agreement with the available experimental values. The current calculations augmented previous theoretical investigations on the ground state and assigned the low-lying excited electronic states of the 1,3,5-C6H3Cl3 + ion. The Jahn-Teller distortion in the excited electronic state for the 1,3,5-C6H3Cl3 + ion were reported for the first time.
