Abstract

Mass-analyzed threshold ionization (MATI) and two-color resonant two-photon ionization methods were used for the determination of the ionization energy (IE) of o-fluoroaniline (OFA) and the vibrational levels of the OFA cation. The MATI spectra were recorded [italic v (to differentiate from Times ital nu)]ia the 00 vibrationless and the 10b1, 16a1, 11 and 121 vibrational levels of the S1 state. The adiabatic IE of OFA was found to be 63644±5 cm−1 (7.8904±0.0006 eV) by MATI spectroscopy. The observed vibrations of the OFA cation include the in-plane ring CCC bending, CH bending, CF bending, CN bending and CN stretching, as well as some out-of-plane ring vibrations. The experimental findings are well supported by ab initio and density functional theory calculations.
