Abstract

REMPI and MATI spectroscopic investigations were applied to van-der-Waals complexes of the three dichlorobenzene isomers with argon. From the REMPI spectra it is concluded that the argon atom is shifted towards the chlorine atoms during excitation for the ortho and the meta isomer while it stays in the middle of the ring for the para isomer. From the MATI spectra it was possible to determine the binding energies in the ion ground state as 617 +/- 15 cm(-1), 529 +/- 125 cm(-1) and 581 +/- 76 cm(-1) for the para, the meta and the ortho isomer, respectively. Together with theoretical calculations binding energies in the neutral ground state were determined to be 426 +/- 16 cm(-1) for all the three isomers.
