Anion photoelectron, photodetachment, and infrared dissociation spectra of Cl-center dot C6H6
Anion photoelectron spectra, photodetachment spectra, and IR-dissociation spectra of the weakly bound chloride-benzene complex have been measured. An upper limit of its stabilisation energy of 0.35 eV has been found, in disagreement with a former experimental value of 0.41 eV and in agreement with a theoretical value of 0.34 eV [C.D. Thompson, B.L.J. Poad, C. Emmeluth, E. Bieske, Chem. Phys. Lett. 428 (2006) 18]. The adiabatic detachment energy leads to a stabilisation energy of 0.26 +/- 0.02 eV. The absence of the linear isomeric structure in the supersonic beam and vibrational assignments of former IR spectra [C.D. Thompson, B.L.J. Poad, C. Emmeluth, E. Bieske. Chem. Phys. Lett. 428 (2006) 18] could be confirmed. New spectroscopic features supply information about the intermolecular stretching mode between chloride and benzene with a frequency of 130 +/- 10 cm(-1).
