摘要：
The resonant two-photon two-color ionization technique has been used to ionize the Aniline molecule and its Van der Waals complexes with rare gases formed in a supersonic free jet. By scanning the ionizing photon energy, ionization threshold have been determined for Aniline and its first two Van der Waals complexes with Argon. The Ar1 complex has an ionization energy 96 cm-1 lower than bare Aniline and the Ar2 complex has an ionization energy 98 cm-1 lower than the Ar1 complex (194 cm-1 lower than bare Aniline). An interesting correlation has been found between the first Ar-complex solvent shift of the IP for a series of aromatic-argon Van der Waals complexes and the IP of the bare molecule. A simple theoretical model is proposed to discuss the observed correlation.
